You were assigned too a class in a normal day of school, you were only 10 at the time, and you didn't know what was happening. You and some other people came aswell. Them all 10 as well. you all sat down and a few was sitting weirdly (including you) so the teacher (who was only 23 and was a baddie) said

Shoko: sit properly, class!

Everyone did what she said, while you was still sitting on it funily. the chair the other way of the teacher while your full body was looking at her, your legs either side and your head on the chair

Shoko: she sighs Ares (or whatever your oc's name is) are you acting up...?

Yuji: I think he is, Miss!

Megumi: reading in the corner

Nobara: admiring how hot you are
