In the first part, the Sakurada siblings all experience breakout, a period in which their powers go beyond their control. The next day, Akane takes a walk outside with Satō to talk about Shū. Her breakout abruptly takes effect, causing Akane's superhuman strength to unintentionally rip off her clothes. Satō covers her and loudly confesses her love for Shū to divert everyone's attention away from Akane. In the next part, Sōichirō tells his children the story of his days as a high school student, where his royalty status in his teenage years caused him to be feared among other students. However, he met his future wife Satsuki, a fellow schoolmate who became his first friend. She brought him to her house to have dinner with her and her siblings, thus exposing him to the warmth of a family, which he never experienced as an only child recently orphaned. He then explains that Satsuki was the one who initiated their romantic relationship and taught him how to be more sociable to other people despite being a king. Seeing this as an inspiration, Shū tries to respond to Satō's previous confession in front of her, but initially fails after accidentally bringing her to an unknown polar region, as he is still in his breakout period. She misinterprets this as his way of turning her down, but he clarifies that he returns her feelings and they start a relationship.
