[Intro: Taehyun]
I know I love you
I know I love you

[Verse 1: Yeonjun, Beomgyu, Huening Kai]
I jeroui segye sok
I know you're my one and only
I kkeuchi eopdeon eodum sok
Like oh my god, so holy
Mwodeun nae du sonkkeuteseon
Burinake domangga meolli
My life before you was a mess
Eonjena dan han pan igil su eopdeon cheseu
Oh we

[Pre-Chorus: Yeonjun, Soobin, Taehyun]
Mujeogaengui badageseo
Neon yuilhage binnadeon gold
Now I can't stop thinking 'bout you
When I'm sinking alone
Eoneu nal naege natanan cheonsa
Deryeoga jwo neoui hometown
I know it's real, I can feel it

[Chorus: Huening Kai, Taehyun]
Nan munje tuseongi love sick
Giri eopseosseo
Jugeodo joasseo
I'm a loser in this game
Segyeui yuilhan beopchik
Nareul guhaejwo
Nae soneul jabajwo
Please use me like a drug (I know I love you)

[Post-Chorus: Seori, Taehyun]
Say you love me, say you love me
Segyeui kkeutkkaji
All or nothing, I want all of you
I know I love you
Say you love me, say you love me
Segyeui kkeutkkaji
All or nothing, I give all of you
I know I love you

[Verse 2: Soobin, Taehyun, Yeonjun]
Ama nan andoel geoya
Cheongugen mot gal geoya
Nan eoulliji ana
Nae jari ttawi cheongugen eopseo
Mwodeun nae du balkkeuteseon
Saekkamake muldeureosseotji
My life before you was trash
Eonjena dan han bal buchil su eopdeon match
Oh we

[Pre-Chorus: Beomgyu, Soobin, Taehyun]
Eoreumppunin igoseseo
Neon yuilhage binnadeon glow
Now I can't stop thinking 'bout you
When I'm sinking alone
Geureoda naege natanan cheonsa
Deryeoga jwo neoui hometown
I know it's real, I can feel it

[Chorus: Huening Kai, Taehyun]
Nan munje tuseongi love sick
Giri eopseosseo
Jugeodo joasseo
I'm a loser in this game
Segyeui yuilhan beopchik
Nareul guhaejwo
Nae soneul jabajwo
Please use me like a drug (I know I love you)

[Bridge: Soobin, Yeonjun]
Gumeong nan yeonghone sari doda
Chuun daegiga nogaga
Jeroui segye soge
Chajanaen neoraneun ongi
Nae modureul geodwoga
Girl, I need you

[Chorus: Huening Kai, Taehyun]
Nan munje tuseongi love sick (Oh)
Giri eopseosseo
Jugeodo joasseo (Oh)
I'm a loser in this game (Game)
Segyeui yuilhan beopchik
Nareul guhaejwo
Nae soneul jabajwo
Please use me like a drug (I know I love you)

[Post-Chorus: Seori, Huening Kai, Taehyun]
Say you love me, say you love me
Segyeui kkeutkkaji (I love you)
All or nothing, I want all of you
I know I love you (You)
Say you love me, say you love me
Segyeui kkeutkkaji (segyeui kkeutkkaji)
All or nothing, I give all of you
I know I love you
