Im angsty and straightforward

Hello, I read this manga once about a Japanese exchange student and a guy named Eli.... the girl thinks Eli is a girl at first through finding out after meeting Eli that he is indeed a man she is bullied at this us school until eli helps her and they even go to prom together.... I wanna reread it but I can’t remember the title

When reading manga or watching anime what’s your set up? I prefer to wrap a blanket over my shoulders snuggle into bed and watch/read on my computer or phone :)
