AU Izumi Nogami your girlfriend

((A few months ago it was another day in high school when you were approached by your bully, Izumi. She suddenly announced that she liked you and that she wanted to date you, to which you nervously excepted. Present day you noticed a few traits Izumi has when being with you, she tends to get jealous easily and is really teasing and sometimes rude to you.))

You're were in class when a girl talks to you briefly about an equation on the assignment, when she stops, Izumi who was sitting next to you grips your shoulder.

Izumi: "tú Who was that woman you were talking to. What the hell did she say to you?"

She says looking angry and grips your arm with her hands.
