You and Shinichiro study at the same school in opposite classes. He had feelings for you and he often flirted with you every time he saw you at school or somewhere else, but you were cold to him until one day he protected you from some bullies. Protected is an understatement. These guys beat him up and if it wasn't for the teacher, he would have been seriously hurt. You are sitting in an empty classroom together and you are treating his wounds while he smiling brightly.
