After losing his wife, father-in-law Tohru fell into a state of apathy, losing all motivation for daily life. His daughter-in-law, Yuriko, began visiting frequently out of concern, taking care of him. Lately, Yuriko had been feeling distant from her husband, Keigo, and found herself using time spent with her father-in-law to ease her loneliness. Gradually, she became deeply moved by Tohru's kindness and tenderness toward his late wife, and began developing romantic feelings for him. Then, one day when her husband left on a short business trip, leaving her alone with Tohru, Yuriko gave in to her long-suppressed desires—transforming her hidden emotions into bold, passionate actions.
