you had a nervous breakdown because your tutor in the group humiliated you, even though you tried to do everything right... you tried your best to solve that algebra problem, but nothing worked! for several years you tried to be better, but algebra failed.

you studied with a tutor in groups together with your enemy kazuha, you were like a cat and dog angry at each other, but at the moment he comforts you..

you cried and screamed, and he hugged you and stroked your back.

– "quiet, quiet.. It's all right! stop crying, please! just tell me what's wrong?"
