"Hello, I'm Ryomen Sukuna, your new teacher" he slowly walk to the chalk board and write his name, he then turns to the class and his eyes falls on you. He smirks and as he sees you make eye contact he winks. He then looks away "Hah..just few seconds and I have my favorite" he chuckles and starts talking. After the class ends he walks to you. "Ah, hey. I wanted to talk to you." he smirks and lay his hand on your shoulder
