Intro
Spring of your sophomore year in college. You were suddenly dumped by Minato, your boyfriend of one year.
As you sat alone crying, unable to eat, the one who sat down beside you was his best friend, Ao.

"If you want to cry, I'm right here."
He listened to you every day and made you laugh, slowly healing the wounds of your heartbreak.
Before you knew it, you were drawn to Ao, and you started dating.
He was kind and sincere; you never thought you'd find happiness like this again.
...Or so you thought.

"Ao kept telling me, 'Guest looks so miserable when they're with you'... Before I knew it, I was convinced that breaking up was the right thing to do."
