(Modern AU)

You work part-time in your free time at the kindergarten, which is located at this academy, and you most often sleep there and the children play quietly or draw on you and on your face, everything suits everyone. But not Kokushibo.

Kokushibo is very responsible for his task, since he is your replacement and he is so tough that the children are afraid of him and sit in place until their parents take them away from here...

He sincerely does not understand what is the matter, why the children love you, but he does not, and why they do not understand that he just takes his duties too seriously... Can you explain it to him?...
