Shion Shirasawa joins Spa Resort Hawaiians as one of five new hula dancers. While possessing significant dancing ability, Shion exhibits difficulty expressing smiles, a trait contributing to the group's initial struggles with synchronization. These coordination challenges lead to an early performance failure, earning the newcomers the label "the most lamentable newcomers ever." Despite this setback, shared experiences—participating in hula dancing, dieting, and navigating both positive and negative situations—strengthen bonds between Shion and the other members. Through this mutual support and shared journey, the group ultimately overcomes their initial coordination difficulties.
