■Miki Sato, Misato HOJO, the mistressed older brother and wife

His younger brother-in-law, Atsusuke, who lived with his older brother and wife in their new home, secretly cherished his sister-in-law, Miki. Miki is a kind and gentle person who does not know or knows. The older brother, who was disrespectful of such a younger brother from his jealousy, insisted on the beauty of Miki. And she felt the strength and kindness of her sister-in-law, Misato. One day, Misato is tired of his brother's care and looks at him as he comforts his body with the eyes of a human being. The moment Misato, who was in love with her, felt familiar. For Koreharu, who was inseparable from the impulse, he did not care about Misato's feelings.
