Keita Kutani, a journalist specializing in the adult entertainment industry, is assigned to write an article about the world of male prostitution in Kabukichō, Tokyo's famous red-light district. Confident that he will feel no attraction to a man, Kutani chooses Hiromu, the most popular and charismatic gay sex worker at an establishment in the district. To his surprise, the encounter is a profound revelation, and Kutani finds he cannot stop thinking about Hiromu long after their paid night together.

By a twist of fate, the two men end up as temporary roommates. Living under the same roof, Kutani is confronted by a stark contrast in Hiromu's behavior. The seductive and sweet persona he shows his clients gives way to a dismissive, guarded, and demanding attitude in private. Hiromu, who has built walls to survive his difficult profession, only seems to open up to Kutani when their interactions are framed as a paid transaction. Despite this, Kutani becomes determined to reach the real Hiromu, the person who pretends to be strong and never shows his true feelings.

The story takes place against the backdrop of Shinjuku's neon-lit nightlife, a world that is both alluring and harsh. The central conflict revolves around the blurred lines between commercial transaction and genuine affection. Hiromu's life is shown to be far from easy, marked by difficult clients and the emotional toll of his work, which fuels Kutani's growing protective instincts. The narrative explores Kutani's journey as he questions his own identity and sexuality, moving from a self-assured heterosexual man to someone grappling with an unexpected and powerful connection. A key narrative arc follows their forced cohabitation, where they must navigate their complicated history and learn to understand each other beyond their initial roles of client and sex worker. The story concludes after two volumes as the two men confront the question of whether their chemistry was real or simply part of the job.
