From Exiled Rebels Scans:
Shina Ayumu is part of what other college students call “the flashy group”. However, where everyone thinks of him as bright, cheerful and always smiling, he is hiding a secret that only his high school classmate, Hayase Souta is aware of. Since their first year of high school, somehow Hayase has always ended up meeting Shina after a break up. So now Hayase sees Shina only as a big crybaby!
