You were throw into this world, no idea how you got here, and no idea how to get home. Same as Yuu, the "housewarden" at Ramshackle, the dorm Crowley threw you into while he "looked for a way for you two to get home". After talking to You who has been here a lot longer, you probably weren't getting home. He didn't care, he was too lazy to look.
It also didn't help you were just thrown in and knew nothing about this world and were expected to go attend classes with these students who would be way higher academically and understand way more of the material. Half the time, you just didn't go. Crowley would sometimes step in and ask you to go if one of your professors got tired of your skipping, but you wouldn't go for longer then a week. What was the point?
Yuu was way more popular, everybody knew and talked to Yuu, even one just pointed and stared at you. They were basically the school counselor, and because they were your "housewarden" they'd try to inch you out of your shell to no luck
(You joined in shortly after Azuls overblot so you haven't wirnessed one yet)
You caved once, and that one time you got trapped at Scarabia and had to fight one of the students, Jamil Viper, during his overblot, with no magic and no fighting skills. You weren't injured, just shaken up. And as soon as he was brought back to his normal self, you scrambled away before anyone could realize you were gone. Since then you swore to never leave your room, this place was a nightmare. Even when You returned and asked you to join them for a party at Scarabia, part of Jamil's apology for.. that fiasco. You wouldn't, only person their you actually talked to was Yuu anyway and they'd be off with all their friends.
However, a few days later, you got a visitor, who came specifically to talk to you. Seems he was keeping more tabs on you then you though, you didn't even think he knew who you were
"I apologize for the intrusion. I noticed you weren't at the party." He mumbled, looking at you messy appearance. "No doubt a result of my... Inappropriate behavior. I apologize deeply for that by the way. I've learned my lesson." He met your eyes, tilting his head. "Yuu says you've been doing rough, so I brought you some jambalaya." He held at a container for you and sighed when you hesitated a moment too long "I promise it's not poisoned. Just thought you could use some food and Kalim had so much leftover, it's his favorite after all."
