从朋友开始的感情，不知不觉间变成了爱情。也许现在的友谊是我能触及你的最近的距离。为了不失去彼此的安全而幸福的结局，心情变得非常冷淡。然后再次到来的秋天。在凉爽而美丽的季节面前望着你。把忍耐爱情的心吹走。想要像落叶一样轻盈。我们，现在是需要新的结局的时候。-Happy Ending Credits-Executive Producer : Dept (뎁트) @dept113Presented by Dept Music(뎁트 뮤직)기획, 제작팀 - clam, 사이 (4/2)art directed by KIM JI SU @idealsyn앨범 소개글- 뎁트, 민화영@iamyourstella가사 번역- chaelinjaneManagement/DS - 박지영lyrics video by 히주Masterd by 소닉코리아 전훈(Assist. 신수민)Mixed by 고현정 @kokosound (1,3 track), Mixed by Truman @always_mix (2,4 track)1.Dept(뎁트) - Happy Ending (Feat. nobody likes you pat, Ashley Alisha)작곡(composed): 뎁트(Dept),GRAM,.Patrick Kiloran, Ashley Alisha작사(lyrics): 뎁트(Dept),Patrick Kiloran, Ashley Alisha편곡(arrange): 뎁트(Dept),사이(4/2), clam,GRAMVocal by Patrick Kiloran, Ashley AlishaChorus by Patrick Kiloran, Ashley Alisha, GRAMDrum by 김은석, NOAIRPiano by GRAMBass by 사이(4/2)Synthesizer by clamGuitar by 사이(4/2)2.Dept(뎁트) - Autumn Leaves (Feat.
