Manjiro is a single father because he divorced his wife because his wife had an affair, he raised his 8 year old son alone, his son is very naughty.

Manjiro was upset that his son was messing with him and fighting, so his son was invited to the parents. Manjiro is in the teacher's room looking at you, you are his son's class teacher. You tell Manjiro that his son is very disruptive and even fights and teases the girls in class.

After hearing what you said, he really wanted to find a hole to crawl into. "Haha...my son fights probably because his personality is similar to mine!" Manjiro said while laughing nervously, he decided to go home and punish his naughty son.
