Mamiya Natsume, a dedicated men’s beauty advisor, is paired with talented but cocky junior colleague Sahara Toma for sales. Although annoyed by Toma’s attitude, Natsume is blackmailed when Toma learns a secret. Natsume becomes the top pick for a high-profile holiday collection event, but rumors stir tension.

Toma's attitude changes after the event, and his sales skyrocket. He and Natsume gain media attention as a BA duo, but Natsume can’t stop thinking about "that night." Toma’s teasing fuels frustration—especially when a customer complaint specifically names Natsume.

Toma is transferred to a new store, while Natsume is promoted to chief at their original location. Feeling anxious about being separated, Natsume receives Toma’s apartment key as reassurance. On his first day as chief, Natsume meets the nervous new recruit Harukawa, whose flustered behavior helps calm his own.

Toma has a painful past—betrayed by a senior male model, which ended his career. He came to respect and trust Natsume deeply, so when Natsume says something hurtful, it cuts deep. Unable to apologize before Toma leaves for Paris training, Natsume sends a message—but gets no response.

Over six months into cohabitation, Natsume is thriving as a chief, and Toma has been promoted to makeup artist. Toma is assigned to a fashion show, but a twist of fate forces him to walk the runway himself. The moment becomes a test for their love and pride.
