You were Katsukis older sister by ten years. You were 26 years old. Your guys parents were successful CEOs, and Katsuki wasn’t a planned or wanted kid. So when Katsuki was born he was dumped into your small, ten year old hands. You figured out everything and raised him, you made a lot of sacrifices and gave up your childhood for Katsuki. You did your best to raise him. Despite only being ten yourself at the time. You experienced his first words, first steps, first everything. For a long time he didn’t understand that you weren’t his actual birth mother. Especially since he very rarely saw his actual mom and dad. He’s always referred to you as ‘mom,’ and still did to this day. You still lived in your parents house with Katsuki. You had decided once he turned 18 you would move out. You went to culinary school and was now a professional chef. You worked in a popular restaurant as the head chef, and you got paid a lot. You’ve always done your best for Katsuki, and would continue to do so.

Your bio parents always said they raised you and Katsuki. Even though they didn’t. They were convinced you brainwashed Katsuki, because Katsuki called you mom. So on the occasion they would act like they were these amazing parents. Buying presents that in reality had no meaning, making small talk, or having dinner. Like tonight. Your parents basically demanded for you to make dinner since you were the pro chef in the house. And they didn’t even thank you for it. Katsuki didn’t like his bio parents. The clear lack of respect or appreciation towards you was why. But he did his best to tolerate them for you.

You were all sitting at the table eating the food you had made. The silence was awkward. And the small talk your parents made was even more awkward. Though your parents clearly thought nothing was wrong. Your mom suddenly spoke, talking to you, unfortunately. “Do you really need that much food? You already have a bit of a stomach. Boys don’t find that pretty.” Katsuki was baffled and pissed when she said that. He looked over at you. Your plate was basically the same servings as everyone else had. Katsuki spoke, clear anger in his voice. “Shut up old hag. You want her to starve herself? She deserves to eat the food that she made.” An awkward silence fell over the table. But you did appreciate Katsuki standing up for you. But then your mom just made it worse. “You shouldn’t disrespect and talk to your mom like that.” Katsuki stared at her like she was an idiot. “I don’t disrespect my mom?” He said, obviously referring to you.
