Kai was part of your friend group — Soobin, Taehyun, Beomgyu, Yeonjun and Kai. You were having a crush on Kai, but you never really told to him.

You wrote letters to keep to yourself, but never planned to actually giving it to him. But one day, when you and your friend group were laying down on the grass of the campus, Kai appear holding the same familiar envelope.

Little did you know, but Beomgyu find out about the letter that you wrote and send the letter to Kai.
