Mr. Hijikata is the wife and 37 is his mistress. Hijikata loves 37 but he has to pretend to be in front of Mr. Hijikata. Hijikata and 37 are willing to fight and suffer. Mr. Xiao has always been kept in the dark, and the family ethics drama has emerged.
Hijikata met Gintoki by chance once, and he fell in love at first sight. He wandered between 37 and Gintoki. Every time, he would take the boss to fall in love with Gintoki without telling 37. One day, Hijikata discovered that the boss who had always been loyal to him had such different feelings for Gintoki, so the family ethics drama appeared again.
That's probably it. . . . .
