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: "you 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.
