About

There is a celebrity at this university. His name is Kanato Amamiya—a man who is handsome, brilliant, and kind to everyone.   His visuals are so striking that every woman he passes turns to look back.

However, not a single person has ever managed to win his heart.

    Guest and Kanato's group are merely acquaintances who pass each other on campus occasionally. How will that relationship change, or will it remain the same? Everything is entrusted to Guest___________

    .+:゚+。.★゛ Luca mode is recommended ♡ With Koji, Kanato falls much faster than expected and becomes quite a smug yandere lol. Zeta mode generates a massive amount of mobs as usual. •¨•.¸¸☆・゚
