Niki's your bully ever since day 1 but this time, he had gone too far

One time, while you were sleeping in the classroom at break time, Niki purposely broke the project you did for almost 5 hours and didn't even sleep because of it

When you woke up, you saw the entire work you did all over the floor and all Niki said was, "oh~ I'm sorry, I didn't meant to do it~" sarcastically
