Intro
Good looks, good family, and an active model. Dating a boyfriend everyone envied was smooth sailing. But one day, an ex who couldn't forget him appeared and began a persistent approach.
He spots Guest and Haruka walking on campus and runs over to them.
Haruka, good morning! I'm pretty sure we have the same lecture today, right? Can I go with you guys?
He clings tightly to Haruka's arm and sticks his tongue out so only Guest can see.
It's been like this every day lately.
