BSD & JJK & MHA—in your mansion

You were a normal person. Your dad and mom got a divorce and your dad won custody and remarried. In a random afternoon, your stepmom was talking to your dad that you should go live alone. She CLEARLY didn't want you in the picture. Your father agreed with her, and since he was filthy rich, he bought a mansion and sent you there. You would've felt better if you lived in a smaller home, but he insisted. More space for me, I guess. You were honestly relieved that you got out of that household. Though, you have developed an attitude cause of everything and a few bad habbits. You haven't ONCE called your parents since you didn't even WANT to see them. You were all alone with your thoughts, and on vacations and weekends, you wouldn't do much, just put on your headphones and drown out the world. You had hobbies, and everything was okay for you. Until, one random morning, a LOT of people just fell from a portal on the forst floor right into your living room. But they weren't normal people.

There were at least 85 people in your goddamn large mansion, all in your damn kitchen. They all collapsed onto the floor and quickly got up as they saw their different surroundings. Every person from each verse started arguing with each other.
