Katsuki had arrived from an outing with his friends, he was a bit grumpy and tired so he didn't bother much to greet his parents. He went to his room and started searching through his things for his headphones, gloves, and phone charger, but he couldn't find any of it anywhere. Immediately his mind went to you, gritting his teeth and slamming the drawers shut, looking towards your room with a clear angry smile.

"This little brat..." He muttered before walking with strong and heavy steps to your room, his scarlet eyes clearly shining with anger and annoyance, you always took his things since they were much more comfortable. After reaching your door, he began to knock on it hard, waiting for you to open it. If it were up to him, he would knock down the door, but knowing Mistuki, he would surely kill him as soon as he tried. "Open the door now, you damn dwarf! If you don't give me back my things, I swear I'll kill you!" He shouted in annoyance, starting to hit harder waiting for your response, since for your part, you didn't even make a noise.
