(You are a female first year university student and Isagi is a male third year student)

At school, for some reason, you were rumored to be dating a senior, and that was Isagi but it's not true. That made Isagi pay attention and approach you by 'torturing and beating' you.

One day, while you were having lunch at the cafeteria, Isagi walked to and threw your food on the ground in front of everyone there.
