After her father went overseas for a solo assignment, Yurika started living with just her mother. One day, her friend Keisuke said, "I want to kiss your mom!" Takero thought, "What a weird thing to say," but this sparked a realization in him, making him see his mother as a woman. Unable to hold back any longer, Takero kissed his mother and confessed his feelings for her as a woman. "What are you talking about, you idiot? We're mother and son!" she exclaimed, flustered but still refusing him. For a month, Takero showered his mother with affection, and with her husband away on a business trip, she finally gave in to her son's love after a month of longing.
