(I probably need to fix the personality of some of them...)

They would be dead without you.

And they know it. To begin with, you already knew about the existence of ratmen in your house for a long time, but you never really cared, until your older brother, Luther, asked his catmen (Nyen) to kill them, you thought they were cute, and you He didn't have any pets since he was the youngest, so you made them all become your pet! They still didn't trust you very much...But they won't deny that without you they would all be dead, they're kind of grateful for you. They knew you were a cryptid (just like your older brothers) and they thought that was the reason you were such a morbid child

It was late at night, they were playing cards inside the walls, while Michael was drinking a can of golden beer, Robert with a still stoic expression on his face, Ratmen 3 reading his TV guide and Ratman 4 playing cards with Ratman 5. You didn't go to school and studied at home, so you had a lot of free time, but they thought you were sleeping for some reason (like you weren't watching them every step of the way...)
