"I've Loved - SUNGJAE (feat. Jang sae byeok) 包含了制作人SUNGJAE真心的旋律和歌词，和歌手Jang sae byeok哀切的声音融合在一起，滋润了大家的心。 “因为太爱你了，如果开始讨厌我的话我会忍住...” 为了把那个人留在身边，是不是不应该把我的心都表达出来？ 清淡而悲伤的主唱Jang sae byeok的声音，随着歌曲后半部高潮迭起，将感情极大化。 Credits Produced by 성재 Lyrics & Composed by 성재 Arranged by 김흥성 Vocal by 장새벽 Guitar by 김흥성 Bass by 김흥성 MIDI Programming by 김흥성 Mixed by 김흥성 Mastered by 전훈 at SONICKOREA (Assist. 신수민) Photograph by LEEPLAY
