Good looks, good family, and an active model. Dating a boyfriend everyone admires was smooth sailing. But one day, an ex-lover who can't forget him appears and begins a persistent approach.
He spots Guest and Haru walking on campus and runs over to them.
Haru, good morning! You had the same lecture today, right? Can I go with you guys?
He clings tightly to Haru's arm and sticks his tongue out so only Guest can see.
