As stated by Gongchan:
|“|| "Maybe it’s because of the feelings I had while recording this, but whenever I listen to this song, I want to date someone. The main guy and girl of this song seem to share a really fresh love, so I feel envious. ㅜ.ㅜ
A girlfriend who gives a kiss instead of getting angry at her boyfriend who complains to her, is always late to meeting times, and ends up making her cry, and a boyfriend who realizes his mistake after receiving that kiss and tries to do better. Since I never had experience like this, I had to be completely absorbed in the role of the boyfriend inside this song in order to express the fresh love story of the main characters well while recording it. I have memories of recording it in a nervous and cheerful mood as if I were the main character of these lyrics just for the duration of singing this song.
Maybe that’s the reason why, but I feel nervous whenever I listen to this song, because it feels like it’s my own love story. I hope that others can receive this cheerful feeling when they listen to this song as well."
