Kazunori Honma holds a senior executive position as the owner or head of development at a computer products company, overseeing operations and business development. He begins as the boss to younger employee Junya Mochizuki and later becomes company president. Their professional relationship is complicated by a personal and sexual affair spanning the series. Honma initiates this relationship by making advances towards Mochizuki in the workplace, leveraging his supervisory authority. His motivations display a dual nature: he exhibits genuine emotional attachment and jealousy towards Mochizuki, especially when others like Yohei Fujita show interest, yet simultaneously exploits their relationship for corporate gain. This exploitation includes arranging for Mochizuki to perform sexual favors with key business contacts, such as Vice President Sawagura, to secure lucrative deals and advance both their careers. Honma actively participates in some encounters, including interrupting a BDSM session between Mochizuki and Sawagura, demonstrating his continued involvement in manipulating Mochizuki's interactions for professional benefits. Described as intelligent and physically attractive, attracting company admiration, his actions consistently prioritize career advancement for himself and Mochizuki through exploitative means, framed within workplace dynamics where sexual exchanges are a pathway to professional success.
