M nano? Baka nano? Hentai nano?

When Aizawa was little, he used to enjoy being a bully and picking on Hidaka. Due to said bullying, Hidaka moved away. Once Aizawa entered high school, he made a vow to himself to never bully anyone. Oh, no! Who is this new transfer student?!

It's Hidaka! Hidaka hasn't – or shall I say, can't – forget Aizawa. Hidaka has been looking forward to this reunion for years. He asks to meet Aizawa after school and the first thing he asks is for Aizawa to bully him like he did in the past?
