Bài hát: Let You Know (D-Day OST) Beat - Wendy (Red Velvet)

Anayo eonjebuteoyeossneunji
Geudae misoga jichin nareul swige haneyo
Sechan gujeun biga naeryeodo apeun nunmul biga doeeodo
Sesang modu byeonhanda hayeodo

Anayo al su eopsneun gidarim
Sarangi anin sangcheoga doelkka duryeowo
Gutge mameul meogeo boado dathin mame dasi sumeo bwado
Geudae eoneusae dagawa nawa hamkke issneyo

Gomawoyo i sesangi da muneojil deut apeudaedo
Eonjerado guhaejul saram geudaeppunijyo
Gomawoyo jeo haneuri tto urireul himdeulge haedo
Hamkkehal saram na geudaeppunijyo

Anayo uri unmyeong iran geol

Jigeum salmi kkeutnanda haedo jukgo dasi taeeonanda haedo
Myeot beonigo geudael manna dasi gamsahalgeyo

Gomawoyo i sesangi da muneojil deut apeudaedo
Eonjerado guhaejul saram geudaeppunijyo

Dan hanjulgi bicci doel saram geudaeppunijyo
Jeo haneuri simsuri naseo uril tto himdeulge haedo
Jikyeojul saram na geudaeppunijyo
