大家好，我们是DAVICHI。 我们一起做过很多事，但却没有一起写过歌。 所以借此机会我们有了这次愉快的合作。 恋爱的开始，应该是谁都经历过或正在经历的苦恼吧？ Lyrics by 다비치 Composed by 다비치 Arranged by 캡틴플래닛   Guitars by 이병호 Keyboard by 최수지 Bass by 박제신 All Programming by 캡틴플래닛   Recorded by 장우영 @doobdoob Studio Digital Edited by 장우영 @MWF Hives Mixed by 강재구 Mastered by 권남우 @821 Sound Mastering (Assist. 유은진) 《지극히 사적인 얘기（A very personal story）》是一首向最好的朋友诉说自己内心对恋爱犹豫不定的歌曲，歌词就像与好朋友的私密对话，想要一起解决烦恼。展现DAVICHI独有默契的旁白和甜蜜的旋律互相融合，编曲既简约又干练，是由与DAVICHI长时间合作并展现了极高音乐默契的Captain Planet负责。
