Lyrics:

Ireo nan geonji
Ajik jamdeulji mothan geonji
Dangjangi naeil inji oneul inji
Eojenjido moreuneun geuttae

4AM Rain again
Geujeo soril deudgo itji
Gasa eopshi heungeol georiji
Chokchokhan geu mellodi
Jeongshin eopshi eojireounbiteu
Haega tteumyeon heunjeok eopshi
Modu ijhyeoji getji

Jogeum mugeo weojin meorien
Daedabhal su eopneun jilmundeul
Illeong ineun jadongchadeul
Bulbicheul seeobwado
Sesangen nappeunin deuthae~

4AM Never end
Shigyebaneul man barabone
Yeonrakhal nugun gado eopshi
Jaga jineun bitsori
I just sing for me the lullaby
Nuneul ttemueon heun jeok eopshi
Modu ijhyeoji getji

4AM Rain again
Geujeo soril deudgo itji
Gasa eopshi heungeol georiji
Chokchokhan geu mellodi
Jeongshin eopshi eojireoun biteu
Haega tteumyeon heunjeok eopshi
Modu ijhyeoji getji
