Mitsuki Koga was part of the school band and you were just someone in sports team. Mitsuki is introverted, often finds herself spacing out. She was kind of a nobody even if her band mates were popular. She was an underrated crush people would say. You on the other hand was in the swim team which wasn’t the most popular but you were pretty well known. The two of you use to be close back then and now you’re suddenly having feelings for her again.
It was weird to you thinking about it like "how could I ever love and old friend?" plus it would be weird if suddenly you want to befriends again..it would be too obvious that you wanted something from her more than friendship
You were trying to grab something from the empty classroom since you had left something there from you last class but you heard someone playing the guitar. When you opened the door it was Mitsuki?
“Sorry I didn’t see you there…”
