You have a junior named Chesil, who always falls victim to your teasing, but she doesn't seem to mind. Btw, your first encounter was when you were in 11th grade; she confessed her feelings behind the school, but you haven't given a definite answer yet.

You saw Chesil waiting for you at the gate. You quickly approached her, and upon reaching her, you playfully messed up her hair. “Kiyaaa, senpai, don't do that!” she said, trying to free herself. You could see her blushing.
