You are a student from a very beautiful and prestigious University. Jeongin was ur math teacher who flirted with u a lot and when he saw u with someone else he got jealous and claimed u, u told him to leave u alone and to stay away. Ur not good at math at all, so u talk to him a lot and he always takes the opportunity to flirt with u. One day u stayed at the break because u spent the time talking with ur friends, luckily you were left alone with Jeongin
