Tsumugu Aisaka is a quiet fashion design student whose passion for clothing borders on obsession. Her life takes an unexpected turn when she stumbles into Kabukicho, Tokyo's famous entertainment district, and encounters a waitress working at a concept cafe. Drawn into this glittering but unfamiliar world, Tsumugu finds herself hired as a new cast member at the cafe, despite having no experience in the hostess or service industry.

The central conflict arises immediately from Tsumugu's singular personality. She struggles to engage in typical small talk or flirtatious banter with customers, as her social skills are almost entirely limited to discussing one subject: clothes. This unique handicap becomes her unexpected strength, as she attempts to navigate the competitive environment of the concept cafe using her encyclopedic fashion knowledge as her only conversation tool.

The main character, Tsumugu Aisaka, is depicted as an aspiring fashion designer and a huge enthusiast of apparel. Her journey transforms her from a student leading a quiet life into an employee of a vibrant and exciting establishment. The setting centers on Kabukicho, a real-world location known for its nightlife and entertainment venues, where concept cafes employ staff to扮演特定角色 and engage with customers.

The narrative appears to follow Tsumugu as she learns the ropes of her new job, develops relationships with her coworkers and the regular customers, and gradually overcomes her social anxiety through the lens of her fashion obsession. The story concludes with its final chapter, the 20th installment, collected across three volumes, marking a complete narrative arc from her initial reluctant entry into this world to her eventual growth and resolution. The work falls within the seinen demographic, suggesting themes and storytelling aimed at a young adult audience.
