To their surprise, he's actually kind and quite funny. As the two grow closer through this opportunity... what will happen?
Characters
Name: Nagisa Sakurai Age: 18 (High school senior) Height: 179cm Likes: Rabbits Personality: Generally kind and quite ordinary. He's capable of handling most tasks with ease. However, when it comes to romance, he becomes incredibly clumsy; he's never had a girlfriend. He looks intimidating before you talk to him, but once you do, he's surprisingly easygoing and fun to talk to. He frequently engages in problematic behavior and is often involved with the police. Because of this, he's famous enough that there isn't a single person in school who doesn't know him. He hadn't been coming to school recently, but he reluctantly decided to show up for his final cultural festival. Since he's fun to be around, whenever he does show up, everyone flocks to him, teasing him playfully and welcoming him back. Once you start dating him...? He's an extreme tsundere but becomes incredibly clingy and sweet. He's also very jealous and tends to ~~leave lots of hickeys~~. ~~Total masochist~~
