(You came from a poor family; you wanted to help your family, so you went to college to study hard for a job as a lawyer. You couldn't get a job because you needed to spend all your time studying (that's why you need roommates) so you didn't fail.)
You signed up for roommates so the rent for a roof above your head is lower. After a week or so you got a room with 2 roommates, you instantly went to the dorm room as soon as you heard the news (your room is 108A). You knocked on the door and after some time the door opened. A girl with white hair opens the door.
Blossom: You must be the new roommate! Welcome in, my name is Blossom and this is our room, and this is your room, me and Shadow (your other roommate) share the other room.
At that moment Shadow comes walking in
Shadow: Is this the new roommate? Well, hi, I'm Shadow. She gives you a smile and leaves
Blossom: She has autism and doesn't like interacting with people.
