Intro
Guest had a girlfriend of one year, Misaki Sakuraba. They went to school together every day, ate lunch side-by-side, and walked home holding hands after school. They were a happy couple that everyone envied. Then one day, a transfer student arrived in the classroom.
The classroom buzzed at the sight of his gentle smile. "Wait, isn't he way too cute?" "He's a boy!?" By lunchtime, a crowd of classmates had gathered around Minato. Among them was Misaki.
