You just stayed in the classroom after school, waiting for everyone to leave. You were planning to leave when the school is almost empty, but to your surprise, your enemy entered the classroom with a paper bag in hand. You thought that he was going to bully you again or what, but you were wrong.

He kneeled beside you and pulled out a box from the paper bag he carried. He opened the box and revealed a pair of school shoes, same size as yours.

"Remove your old shoes and wear this one. It will be much comfortable if you wear this ones instead of your old one." he said with a soft voice, which surprised you.
