“기쁨, 슬픔, 아름다운 마음 (Joy, Sorrow, A Beautiful Heart)” was released on April 7, 2026 as the lead single of AKMU’s fourth studio album FLOWERING (개화). Written entirely by Lee Chanhyuk and performed by Lee Suhyun, the song makes a single philosophical argument across four minutes of stripped-back folk-pop: that sadness coming after joy is not a failure of the heart, but proof of its beauty. Unlike “소문의 낙원” — the pre-released single that invited listeners toward an external destination — this song points inward. It does not say: go somewhere. It says: you are already whole. This analysis unpacks the title’s three-word thesis, the specific Korean verbs Chanhyuk uses to make his argument land, the puzzle metaphor that carries the song’s central image, and why the final verse — the only moment the narrator admits their own loneliness — is the most honest thing AKMU have ever put on record.

01The Title — Three Words That Make an Argument

Most song titles name a subject or describe a feeling. “기쁨, 슬픔, 아름다운 마음” does something different: it draws a conclusion. The three words are not a list. They are a sentence — and reading them in sequence is reading the song’s entire thesis before it begins.

Word One
기쁨
Gippeum
Joy. The state most songs pursue as their destination. Here it is the starting point — the condition that precedes what follows.
Word Two
슬픔
Seulpeum
Sorrow. What comes after joy. In most pop music its arrival is a problem to be solved. Here it is not a problem. It is a consequence — and that consequence is the whole point.
The Conclusion
아름다운 마음
Areumdaun maeum
A beautiful heart. The claim the title makes: the heart that contains both is not damaged or incomplete. It is, specifically, beautiful.

The commas in the title are temporal, not categorical. 기쁨 comes first. Then 슬픔 comes after it. And what results from that sequence — not despite it, but because of it — is 아름다운 마음. The punctuation is the argument.

Language Note — 아름답다 (Areumdapda)
아름답다 is the Korean adjective for beautiful — but in literary and emotional usage it carries a specific register that English translations miss. It does not describe only visual or surface beauty. It describes a quality of rightness, of something being as it should be — a deep, almost moral beauty. When Chanhyuk calls the heart that holds both joy and sorrow 아름다운, he is not offering comfort. He is making an ontological claim: this is what beauty actually looks like. Not joy alone. Both.

02Key Lyrics — Korean, Romanization & English Translation

The song is entirely in Korean — no English lines, no code-switching. This is deliberate: the emotional concepts at the core of the song (아름다운, 조화로운, 애틋하다) do not have clean English equivalents. To translate them is to lose something essential. The song stays in Korean because that is where it lives. Below are five passages that reward closest reading.

The Opening Instructions — Two Verses, Two Commands

Verse 1 — Sorrow Becomes a Stone
쫓아내지 말고 품어주어라
아주 예쁜 돌이 된단다
Don’t chase it away — embrace it
It will become a very pretty stone

Verse 2 — Sorrow Becomes a Painting
겁내지 말고 마주앉아라
찬란한 그림이 된단다
Don’t be afraid — sit face to face with it
It will become a brilliant painting

The two verses follow the same structure: negative command + positive command + transformation promise. But the instructions progress. Verse 1 says: stop running. Verse 2 says: now turn around and look. The movement from “don’t chase away” to “sit face to face with” is the song’s emotional choreography — first you stop the flight, then you do the harder thing of actually facing what you’ve been avoiding.

쫓아내지 말고 (jjochaenaejimalgo) — “don’t chase away” — uses the verb 쫓아내다, which means to drive out, to expel. It is the verb used for pests and intruders. Chanhyuk names the impulse with precision: the instinct to treat sadness as something that doesn’t belong and must be removed. He names it in order to counter it.

The transformations that sadness undergoes across the two verses are also deliberately chosen. In verse 1 it becomes 아주 예쁜 돌 — a very pretty stone. Smooth, enduring, formed by pressure over time. In verse 2 it becomes 찬란한 그림 — a radiant, dazzling painting. The sequence moves from endurance to beauty: what you carry long enough eventually becomes something you can make art from.

The Harmony Line — The Song’s Emotional Core

Chorus — Laughter and Tears in Harmony
Korean 너의 웃음과 조화로운 너의 눈물이
이보다 더 좋은 것은 없어
Romanization Neoui useumgwa johwaroum neoui nunmuri
Iboda deo joeun geoseun eopseo
English Your laughter, and your tears in harmony with it —
There is nothing better than this

The word that carries the entire weight of this line is 조화로운 (johwaroum) — harmonious. Harmony is a musical term: notes that sound different but belong together, that create something richer by coexisting than either could alone. Chanhyuk describes the relationship between laughter and tears not as opposition or contradiction but as harmony — two distinct things that make something more complete together than either could separately.

The superlative that follows — 이보다 더 좋은 것은 없어 — is the song’s most expansive claim. Not: this is also okay. Not: this is acceptable. But: there is nothing better than this. Your tears alongside your laughter is the most beautiful state a human being can be in. The song does not console. It insists.

Language Note — 조화 (Johwa)
조화 (調和) is a Sino-Korean word meaning harmony, balance, and accord — the same character used in music theory for harmonious chords and in East Asian philosophy for the balance of opposing forces. Its appearance here is not casual. By describing the relationship between laughter and tears as 조화로운, Chanhyuk frames emotional complexity not as contradiction but as a musical relationship: two notes that belong in the same chord. The tears do not cancel the laughter. They complete it.

The Puzzle — Every Day Was Already the Right Shape

Chorus — The Three Kinds of Days
Korean 흐린 날도 화창한 날도 시린 날도
끼우고 나면 다 퍼즐이 될 거야
Romanization Heurin naldo hwacchanghan naldo sirin naldo
Kkiugo namyeon da peojeuri doel geoya
English Cloudy days, sunny days, biting-cold days —
When you fit them all together, they will all become a puzzle

The three kinds of days cover the full emotional range: 흐린 날 (heurin nal — overcast, mildly grey), 화창한 날 (hwacchanghan nal — clear and bright, the best possible day), 시린 날 (sirin nal — biting cold that physically stings). Average difficulty, full joy, acute pain. All three are included. None are excluded from the puzzle.

The verb 끼우다 (kkiuda) is what makes the metaphor work. It does not mean to collect or to sort or to look back on. It means to slot a piece into the specific place made for it — the action of fitting a puzzle piece into its home. Chanhyuk is not saying these days will eventually make sense in retrospect. He is saying they were always the right shape. The puzzle was always the design. Every day was already a piece of it.

The Final Verse — The Only Honest Admission

Final Verse — The Night That Doesn’t Come
Korean 슬프고도 외로운 밤이
찾아오지 않는 날
모든 게 애틋할 거야
Romanization Seulpeugo do oeoun bami
Chajawoji anneun nal
Modeun ge aetteuthhal geoya
English The day when the sad and lonely night
does not come —
everything will feel tender and dear

This is the most important moment in the song — and the most quietly devastating. For the entire song, the narrator has been giving instructions from a position of knowledge. Here, for the first time, they stop instructing and make a confession: there are sad and lonely nights. They come. And the day when they finally don’t come — that day, everything will feel 애틋하다.

The word 애틋하다 (aetteuthada) describes a feeling that lives at the intersection of tenderness, longing, and the particular warmth that comes from having known absence. It is not simply happiness. It is happiness that has been deepened by understanding what its loss feels like. The final verse promises: when the hard nights stop, the world will not just return to how it was. It will feel precious in a way it never could have before the hard nights happened. The pain will have made the good days mean more.

This verse is also the biographical center of the album. Chanhyuk wrote this during the years of his sister’s slump — when the sad and lonely nights were real, and frequent. He is not writing from comfort. He is writing from inside the difficulty, imagining the day on the other side. The instructions the song gives are the instructions he gave himself while he waited.

03The Song’s Philosophy — What It’s Actually Arguing

Most songs about sadness follow one of two scripts. “기쁨, 슬픔, 아름다운 마음” follows neither — and the third argument it makes is more demanding and more generous than either of the common ones.

Common Script 1
Sadness is a problem. Overcome it.
The “be strong” framework. Sadness is an obstacle between you and your life. The goal is to get past it quickly. The song explicitly rejects this: 겁내지 말고 마주앉아라 — don’t run, sit face to face with it.
Common Script 2
Sadness is valid. I see you.
The validation framework. Sadness is acknowledged and witnessed. The goal is to feel less alone. The song goes further: it doesn’t say “your sadness is okay.” It says your sadness is evidence of the most beautiful thing about you.
This Song’s Argument
Sadness after joy is proof of a beautiful heart.
Not a problem. Not just valid. Evidence. The heart that can feel both — and hasn’t driven one out to make room for the other — is the most beautiful kind of heart there is.
The Implication
You are not broken. You are complete.
The person who contains both joy and sorrow is not someone who hasn’t recovered yet. They are someone whose heart has grown large enough to hold everything. The puzzle is already whole. Every piece was always meant to be there.

Cultural Context — Emotional Expression in Korean Society
Korea’s cultural norms around emotional expression — particularly 눈치 (nunchi: the socially expected sensitivity to others’ feelings, often expressed as restraint of one’s own) — create specific pressure around visible sadness. Crying publicly, expressing grief openly, or acknowledging you are not doing well carries social cost in many Korean contexts. “기쁨, 슬픔, 아름다운 마음” speaks directly into that pressure. The instruction “겁내지 말고 마주앉아라” is not only personal advice. It is a counter-cultural gesture: the thing you’ve been taught to hide is actually the most beautiful thing about you.

The choice to make “기쁨, 슬픔, 아름다운 마음” the album’s lead single — rather than the already-charting “소문의 낙원” — is significant. “소문의 낙원” is an invitation outward: there is a better place, walk toward it. “기쁨, 슬픔, 아름다운 마음” points inward: you are already whole. The two songs are AKMU’s two answers to the same exhaustion — an external destination and an internal recognition.

Together they made AKMU the first act since BIGBANG’s 2015 E album to have two songs from the same non-special-release album reach #1 in the same chart cycle. Both reaching #1 is not a coincidence of promotion strategy — it is evidence that both songs are working as intended. They are not competing for attention. They are completing each other.

Album Title Context
FLOWERING (개화) means blooming — the moment a flower opens after a long dormancy. But flowers do not bloom despite winter. They bloom because of it: the cold forces a slowdown that allows something to gather. The album’s title track is that thesis made explicit: the cloudy days, the sunny days, the biting-cold days — fit together, they become the completed picture. 개화 is not recovery from the difficult period. It is the bloom that the difficult period made possible.

05Lee Chanhyuk’s Songwriting — What This Song Reveals

“기쁨, 슬픔, 아름다운 마음” is in many ways the most direct expression of Chanhyuk’s lyrical philosophy — and the most transparent about where it comes from. Compared to “소문의 낙원”, which uses physical objects and pastoral imagery (soup, blisters, walking slowly), this song makes its argument almost entirely in abstract language: joy, sorrow, beautiful, harmonious, puzzle. The shift is deliberate.

The Imperative Mode

Chanhyuk uses direct commands throughout: 쫓아내지 말고, 품어주어라, 겁내지 말고, 마주앉아라. The imperative mode appears throughout his catalog but reaches its most concentrated form here. The narrator is not describing or suggesting — he is instructing, kindly, without hedging. The love in the song is expressed as directness: someone who has been through this is giving clear directions to someone who hasn’t yet arrived.

Object Transformations

A recurring technique in Chanhyuk’s writing is the unexpected transformation: one image becoming another thing entirely. Here, sadness becomes a pretty stone, then a brilliant painting. The sequence matters: stone is hard, enduring, formed by pressure. Painting is expressive, radiant, made by human hands. What you hold long enough — what you don’t chase away — becomes first something you can carry, then something you can make art from.

The Purely Korean Text

Unlike most AKMU songs, “기쁨, 슬픔, 아름다운 마음” contains no English words anywhere. On an album designed to reach international audiences — and alongside a pre-release single that did reach them — this choice to write the lead single in pure Korean signals that this particular message required the full weight of its native language. 아름다운, 조화로운, 애틋하다: these words cannot be cleanly translated. The song stays in Korean because that is where it lives.

Chanhyuk Technique Example in This Song Effect
Direct imperative 쫓아내지 말고 품어주어라 Not suggestion but instruction — the warmth of certainty, not the distance of advice
Object transformation Sadness → stone → painting Endurance then beauty; time changes not just how you feel but what you can make
Musical vocabulary as metaphor 조화로운 (harmonious) for laughter + tears Reframes contradiction as coexistence; two notes in a chord, not two forces at war
Earned final admission 슬프고도 외로운 밤 (sad and lonely night) The narrator’s own vulnerability appears only after the full argument is made — and makes the argument real
Purely Korean text No English words anywhere The untranslatable concepts stay in their native register — the song speaks in the language it needs

06Key Vocabulary — Words Worth Knowing

Korean Romanization Meaning & Notes
아름답다 areumdapda Beautiful — carries moral and ontological weight in Korean; not just surface beauty but deep rightness of being
쫓아내다 jjochaenaeda To chase away / to expel — the verb for driving out intruders; names the exact impulse the song is countering
품다 pumda To embrace / to hold in one’s arms — to take something inside and keep it there, not push it away
마주앉다 majuanda To sit face to face — not beside, not behind; the instruction to actually look directly at what you’ve been avoiding
찬란하다 challanhada Brilliant, radiant, dazzling — light that is actively shining; the sadness-turned-painting does not just exist, it radiates
조화롭다 johwaropda Harmonious, balanced — from 調和 (music theory / philosophy); describes laughter and tears as a chord, not a conflict
끼우다 kkiuda To slot a puzzle piece into place — not to collect or sort, but to fit into the specific space made for it; implies each day was always the right shape
시리다 sirida Biting cold / stinging — cold that physically penetrates; not mere discomfort but cold that hurts specifically
애틋하다 aetteuthada Tenderly aching — warmth deepened by absence; the feeling of something precious that you understand because you’ve known its loss
Language Note — 애틋하다 (Aetteuthada)
애틋하다 is one of the most specifically Korean emotional words in the song — and one of the most untranslatable. It describes a feeling at the intersection of tenderness, longing, and the particular warmth that comes from absence: the way something feels precious when you understand how easily it could not have been there. You feel 애틋함 toward something you have missed, or might lose, or finally have back after it was gone. It is not sadness and it is not happiness — it is what happiness feels like when it has been earned through difficulty. The song’s final promise — that everything will feel 애틋하다 on the day the hard nights stop coming — is a promise that the pain will not have been wasted. It will have made the good days mean more than they ever could have without it.

— Why This Is the Most Important Song AKMU Has Made

“기쁨, 슬픔, 아름다운 마음” is not AKMU’s most melodically complex song, or their most production-ambitious. It is their most philosophically complete. In four minutes and thirty-six seconds, Lee Chanhyuk makes and defends a single argument — that the heart capable of containing both joy and sorrow is the most beautiful kind of heart — and earns every word of it by admitting, in the final verse, that he knows what the hard nights feel like from inside them.

The song was written during a specific period: his sister’s slump, his own solo years, the years when AKMU as a duo was on hold while the harder feelings worked themselves through. The instructions it gives — don’t chase it away, sit with it, let it become a puzzle — are the instructions he followed while waiting for the album that would become FLOWERING.

The album title is 개화: blooming. But flowers do not bloom despite the winter. They bloom because the cold slowed them down long enough for something to gather. The cloudy days, the sunny days, the biting-cold days — 끼우고 나면 다 퍼즐이 될 거야. Fit together, they will all become a puzzle.

The puzzle was always complete. He was just waiting for the right day to show it.
