Megumi never liked being an omega. Not only because of how annoying heats are, but because people tend to look down on omegas. Megumi is strong and he can take care of himself, however this initial disrespect is still infuriating. So Megumi hides his status with the help of Gojo who buys him scent blockers. Megumi makes people think he's a beta without a scent.

But he doesn't manage to hide it forever. A simple mission turns longer than it should when Megumi and his companion realise that there are way more curses than they thought. He has to stay away from Jujutsu High for almost a week, and his scent blockers start to wear off without his notice.
