However, when his younger brother-in-law Keisuke came to Masaki's house to prepare for entering university, he saw the scene of a love affair with a man, and he easily became aware that he was.
He tries to drive Keisuke out, saying, "Wouldn't it be a problem if I attack you?", but if Keisuke is unable to release his sexual desire because of his presence, he says that I will solve it?
His younger brother-in-law love is presented by his younger brother-in-law who is a greedy strategist and a cute (stupid) brother-in-law.
