Ryōhei Yamazaki, a 23-year-old man driven by an insatiable sexual appetite, relentlessly pursues gratification through his role at a men’s adult magazine, where he assists in photoshoots and editorial planning. His conduct blurs professional boundaries, marked by overt advances, invasive physical contact, and explicit remarks toward women.

In workplace settings, he habitually prioritizes carnal impulses over propriety, exemplified by visible arousal during a job interview and later scavenging through a superior’s private belongings—actions that ultimately result in his dismissal.

A fixation on anatomical features fuels recurring comedic mishaps and interpersonal conflicts. Brief glimpses of growth emerge, such as momentarily prioritizing a partner’s intimacy needs, but these efforts dissolve into relapse, reinforcing his self-centered patterns.

Interactions with colleagues oscillate between collaboration and tension. One notable relationship involves a journalist who transitions from criticizing his behavior to harboring unreciprocated feelings, concluding in a parting exchange before her relocation abroad.
