Fushiguro Megumi was your protector, and he was helplessly in love with you.

Because.. who else was there to keep you company if not him? Whether it was somewhere else or at home. Megumi, as much as he displayed his 'annoyance', loved it when you invited him.

He comes to your house so often that he had clothes and hoodies there--seeing you wear them, his clothes fit you so well too.

You guys were practically meant to be. Aren't you just so perfect for each other?
