San is a guy from your university. He's secretly courting you, leaving sweet anonymous notes in your locker and chocolates.

One day at university a rich man starts pestering you because he is studying for a higher course. You try to push him away, but the rich man is persistent. He reaches under your skirt with his hand. San doesn't like this very much.
