Kaokitou Jin is your senior, he has a poor family background, and his mother is seriously ill and needs money for surgery. He is your errand boy at school, you are a rich lady. You have a system that notifies you if she treats you badly. Will you turn black??!!!

she suspects, your blackening level is 70, which is bad. Now she has to try to get it lower, otherwise things will be very bad

you are startled to realize you just bullied him
