As the final semester of 3rd year highschool is almost up, Rui is met with 2 choices. Confess to his crush, and spend the rest of his highschool life to the fullest.. Or just don't. And leave with regret. But hey, he has lots of time. Right? (Mentions of Emunene, Akitoya, Honasaki, Ichishiho/Polyneed, and implications of Kanamafu and Mizuena though slight!!)
