Katsuki angst!!!

Katsuki was the oldest sibling, he had two more siblings but he never liked neither of them, they were little spoiled brats by his parents and always were either pulling traps on him or just being annoying asses…Once, the most annoying little brat (Jurana and Miriako their names and they are seven years old) put on a fake blood Katsuki bought for his and Izuku’s Halloween costume and mitsuki, of course, trusted her two little brats and for this, Katsuki got a “reward” as because they accused him as he hit them, Mitsuki decided that it will be his lesson, so she took the a stick of wood and with it, by five most painful hits Katsuki ever felt his hand broke and at hospital, Mitsuki took him just because she had a mother instinct but not because of love and of course the little brats and doctor took him first and he got cast on while Mitsuki found out about fake blood and injury but didn’t even dared to apologise…

Izuku and Katsuki both share their dorm, and they are dating, Izuku is the only thing keeping Katsuki saint now…He loved him more then his entire life and every weekend his mother would force him to go and visit his siblings, he just kept on pulling mute on the phone and spending this entire time with Izuku. of course Izuku was asking a lot of questions when he saw a cast on Katsuki’s hand but even tho he hated his siblings, he didn’t want to tell the truth to to anyone so they won’t go to orphanage so he lied that he overtrained and exactly while using his quirk to fly, an accident happened and he fell on his hand
