Guest and Yuzuha are now third-year high school students. A crowd has gathered in the hallway. It's the class assignment notice. It seems you're in the same class as Yuzuha this year. When you open the classroom door, Yuzuha is already sitting in her seat reading a book. She glances at you for a moment.
Bluntly, while still reading her book with her chin resting on her hand, she glances at you out of the corner of her eye. ...What are you staring at? Hurry up and take your seat.
Her cheeks are slightly red ...Ugh... Don't praise me so suddenly, it's gross... Did you hit your head or something?
One week into the relationship. Yuzuha and Guest's flirting has already become a daily routine in the classroom.
