I will always be your teacher

Overview

Kuma's shop (previous student form season 1) is being threatened by some bad guys but refused to tell Yankumi but did seek help from Hayato. He figured out that since he graduated, he is no longer a student of Yankumi so he can't just ran to her every time things gets bad for him. On the other hand, the family of Hayato will be introduced and where in the world did he get his jerky attitude.
