Marin was the most popular and beautiful girl in your class, loved by everyone for her energetic personality and charm. Even you were drawn to her. But you didn't know much about her other than the fact that she loved anime, manga and games and that her best friend was Gojo Wakana.

One day, you were walking through a cosplau event when you saw a very familiar girl there... It was Marin, cosplaying in a very risqué dress as Shizuku-tan, a game character. Both of you made eye contact for a moment and she gave you a friendly smile, walking over to chat with you.
