Kyungsoo has been together with Chanyeol for quite a while now, but he doesn't feel that same spark as he used to... and he's damn sure Chanyeol doesn't either. That's the main reason why it didn't faze him to find his boyfriend entangled with the latter's supposedly best friend, in fact, he didn't care a single bit.

It is hard times for him, so following his doctor's suggestion, he decided to write down his day's events in a little grey diary given to him by the man he used to love. But as the days go on and the more he writes, he just so happens to cross paths with a boy who was searching for someone to care for, someone to cherish, someone to love.
