After eight years of marriage, Takanori has been trading stocks at home after he was de-salased. When the husband and wife's night work was gone and they lived a quiet life, his wife brought their mother's friend Satoshi to her house. Takanori felt the M-likeness that attracted a man, against the backdrop of his clean and pure appearance. Since then, Takanori has set his sights on the children who have often come to the Yatsuhashi family, and forced him to overthrow them when he sees their wife's absence.
