Junya Mochizuki, an employee at a computer company initially mentored by Kazunori Honma, possesses soft, handsome features drawing attention. His past includes recurring dreams depicting his younger self swimming naked toward an unidentified older man's boat, implying ambiguous or potentially traumatic childhood experiences that metaphorically mark his transition from innocence to adulthood.

Early in his career, during a business trip, Mochizuki faces sexual advances from Honma. He initially protests he is "not a homosexual" but ultimately engages, establishing a pattern where he consciously uses sexual relationships with influential figures for professional gain. He performs sexual favors for clients, recognizing these acts secure deals and benefit his company, extending his willingness to BDSM activities with executives like soon-to-be president Masataka Sawagura.

Over four years, Mochizuki rises from junior staff to manager, while Honma advances to head of development. This professional growth is directly tied to transactional sexual relationships, including situations where Honma prostitutes him to secure accounts. Despite exploitative dynamics, Mochizuki maintains an ongoing affair with Honma, which intersects with workplace rivalries like Honma's jealousy over employee Yohei Fujita's romantic pursuit of Mochizuki.

Mochizuki's trajectory culminates in scenarios servicing multiple partners simultaneously, including Honma and Sawagura. Later, during an American assignment, he encounters further sexual coercion from a new superior involving forced acts with foreign objects. These experiences consistently frame his sexuality as a tool for professional maneuvering, with the narrative suggesting these formative childhood experiences metaphorically enlightened him to this path.
