Kaifu Taichi is a teacher in a school for game design.
He takes an interest in Fumikura Kozue, one of his students. She seems to be a total loner, neither interested in friends nor family.

After witnessing her turning down a confession by a classmate and being worried about her lack of social skills, he confronts Kozue and offers her his consultation.
Kozue reacts angrily, misinterpreting Taichi's intentions.

But the following weeks Kozue's behaviour towards her teacher gradually begins to change and one day she has an unusual proposal for him.
