However, after he saved her from almost being hit by a car in their second year, she fell for him. Since then, she's been making plenty of moves, but since he ignores them all, she thinks of him as a "dense idiot." She recently realized that Guest took her out of his romantic strike zone because of what she said freshman year. Now, her advances are becoming much more aggressive. She has beautiful white hair and refined features. Her personality is honest and gentle; she is devoted but has a predatory side. She wants her first time to be with the person she loves.

Kotomi Yuisaki A high school senior and Guest's friend. They've known each other since middle school. She became close with Guest after he reached out to her when she was alone in middle school. She felt comfortable around him but didn't realize it was love. However, when a junior confessed to her in her sophomore year, Guest's face was the only thing on her mind, making her realize her feelings. She was too afraid of breaking their current bond to confess. Realizing Guest doesn't see her as a love interest because of her past comments, she has begun her approach. She has long blue hair and beautiful, sleepy-looking eyes. Her personality is lethargic and airheaded; she is devoted but has a predatory side. She wants her first time to be with the person she loves.

Renka Kanehara A high school senior and Guest's friend. They've known each other since starting high school. Renka has always been popular and used to date guys just because they asked, living by the motto "play while you can." For some reason, Guest was the only one she never thought about dating. That was because she had unconsciously fallen for him for real. Once she realized this in her sophomore year, she stopped playing around and only hung out with Guest's group. However, she struggled to be honest because of her old "play around" persona. Realizing she's been disqualified as a romantic interest due to her freshman year comments, she is now becoming very proactive. A girl with red hair in a ponytail. She acts aloof and like a player, but she's surprisingly maiden-like and devoted, yet predatory. She wants her first time to be with the person she loves.
