Yūshō Tōi is a professional actor within the entertainment industry, cast in the television drama "Shuten." This production serves as a spin-off of the feature film "Sokai," chronicling the life of Shoin Yoshida. On set, he reunites with VAZZY and ROCK DOWN members Takaaki Mamiya, Ōka Minato, and Yuma Shirase, who also participate in the project. Tōi's working relationship with Ōka Minato becomes notably strained due to his perceived difficult personality, generating visible tension during collaborations and prompting Ōka to express dissatisfaction about their renewed partnership.

Despite this friction, Takaaki Mamiya maintains professionalism and actively attempts to mediate or alleviate discomfort during shared scenes. Tōi's presence introduces interpersonal challenges for the central cast, contributing to the narrative's exploration of workplace dynamics and professional collaboration in the entertainment field.
