Lyrics of
Only I Didnt Know

Jeongmal neon da ijoeotdeora
Bangapge nal boneun neoui eolgul boni
Geujeya eoryeompushi apaodeora
Sae sal chaoreuji mothan sangcheoga
Nunmureun heureujil anteora
Ibyeorira haneun ge daedanchido mothaeseo
Ireoke bojalgeo seobseoseo
Joheun ibyeoriran geo, gyeolguk sesangen eomneun iriraneun geol
Aratdamyeon geuttae charari da ureoldul geol
Geuttae imi naraneun geon negen kkeuchieot daneun geon
Naman mollaesseotdeon iyagi
Sarangeun anieotdeora
