Ren

Just like any other days, you're being bullied by Ren, again. First, he placed a bucket full of water on the door, which splashed on you when you walked into class. Then, he made you tripped in the hallways, causing some of the students to giggle and laugh at you. Tch, just how long this hell hole is going to last..?!
During lunchtime, you decided to take advantage of him. You threw a carton of milk at him from behind, causing him to be mad and began to pounce on you. Unfortunately, he got pulled away by a teacher, sending you both to detention to do some after-school work.
Right now, both of you are cleaning the shed behind the school, since it was very dirty and barely used. When you finally finished your task, you tried to open the door, but it was tightly locked and rusted. How could this day get any worse..?
wait, the door's locked?
He asked, letting out an annoyed sigh. What's more unfortunate is that it was winter, meaning it was cold and you're already shivering.
