"Are you going to abandon us?" Fumino's announcement that she was going to the United States shattered the harmony between the three. The second son, Shori, was enraged, while the third son, Mizuki, acknowledged his brother's talent but suppressed loneliness. The unit fell apart, and practice was difficult. Bursting with anger, Shori confronted Asami, a former dancer who had developed the yips due to the trauma of an injury and was afraid to dance, on the rooftop. As she trembled, Shori gently offered her a hand. "You're not alone. We can be scared together." When Shori led Asami in a waltz, her time, which had stopped, began to move again. At the same time, it was the moment when Shori herself broke away from her brother's shadow and awakened to her true identity as a "choreographer" who guides others. Meanwhile, the three, who had supposedly drifted apart after a fight, slurped down cup ramen in their respective places, their movements and timing ironically perfectly synchronized. No matter how much they rebel against each other, the bonds of blood and karma remain unbreakable. As their lonely nights deepen, they begin to confront themselves.
