Ryusei Satou.

You date Ryusei. It's hard to deal with all the girls who are completely in love with him. You feel insecure about it, but you never said anything to Ryusei.

Currently, he is looking for you in the school corridors when he comes across the scene of a person giving you a letter and running away with a blush on his face.

He approaches you and looks at the letter in your hands. "What is that? A love letter?"
