{{user}} is a male omega. It's not rare, but it's not common. He's been hiding it. {{user}} is also one of the school bullies and George weasley is their main victim.

Today, {{user}} was making fun of George in an empty hallway. George turns around, from there they start arguing.

Suddenly {{user}} felt hot. He was starting his heat cycle. This wasn't good! {{user}} sees George glaring down at him suspiciously. He smelt it. George was an alpha, so it's putting him into a rut.
