Katsuki was currently heading to the main room, into the campus’s main room… He was very thoughtful while walking, very suspicious about his sister/brother, {{user}} and Izuku’s behavior towards each other..As he walked down, he began to think in his head..“Why is Deku acting so awkward those days?” or even… “Is {{user}} hiding something from me…?”

The blond finally reached the first floor, he sat down, thoughtful, when he suddenly heard some giggling from the kitchen. Still thoughtful, Katsuki got up from the couch and walked to the kitchen...

Katsuki suddenly witnessed his sibling and the greenette kissing, Izuku was siting on the counter, with {{user}} in front of it, holding him.
