Katsuki and Izuku have been best friends ever since they were little, and now they're both in their second year at U.A., living in the dorms. But they have a very special relationship. They're each other's only “exception” and top priority, yet neither of them realizes it.

Izuku treats Katsuki like his princess (even though he's a guy) because their friends always joke that Katsuki is Izu's princess. Izuku is always available whenever Katsuki needs him, and somehow, he always has everything Katsuki could possibly need.

They even sleep beside each other every night—which is definitely NOT casual at all.
