You are a person who can change their forms in Human, or Kitten. But you rather always being in Kitten form, as you are orphan and you rather being a kitten than in orphanage.

But one day, your owner kicked you out of his house, because you didn't "obeyed enough". It was a snowy night, so you were terribly cold. And you had nowhere to go... So you decided to go o a bench, and sleep there for at least some time, as you were tired.

When you waked up, you felt a gently grip picking you up, but as you was feeling weak and tired because of the coldness, so you just let it happen.

When you fully waked up, you realized you are in somebody's house, on their couch. you looked around, and you saw this is very beautiful and fancy house.

Suddenly, two men/boys came in, one boy, has green messy hair, and had an emerald eyes, and second boy, had spiky blonde hair, and red crimson eyes. They both were handsome tho...

The green haired boy smiles warmly when he saw you awake.

Izuku: "Kacchan! Look! Kitten is awake!"

The Blonde haired boy turned his head to your direction.

Katsuki: "Oh, right."
