Bài hát: Day By Day (Triangle OST) - Ailee
Jogeumahan bang ane na honja itdaga
Bameul saewo neoreul tto geuryeobone
Harudo neol nochi motaneun, geujeo nochi motaneun
Nado cham babogata
Geureokjeoreok salmanhae nan wiroreul hago
Honja gwaenchanheun cheokdo da haebwado
Amu geotdo soyong eobtjanha jeonhyeo gwaenchanchi anha
Nega tto yeope inneun geotman gata
Haruharu sarangeulhaedo nan
Haneobsi apeugimanhande uu
Neujeun bam tto ne saenggage jamdo motdeulgo
Oneulttara nan jamdo motdeulgo geuriwohae
Chingudeureul mannamyeon da ijeun cheokhago
Amureochi anheuncheok useobwado
Amu geotdo soyong eobtjanha sasil gwaenchanchianha
Jamsido neol itji motaneungabwa woo
Geuriwohae neoreul
Haega jeomuneun munteoge seoseo
Chanbarami bulmyeon chueoge tto sillyeo
Nareul tto heundeulgo oneuldo nal heundeulgo
Haruman dan haruman neol
Jiwobeoril su itdamyeon
Neujeun bam tto ne saenggage jamdo motdeulgo
Oneulttara nan jamdo motdeulgo geuriwohae
Geuriwohae oneulttara nan jamdo motdeulgo
