A senior colleague in the sales department. Five years older than the protagonist. He has black hair with incredibly strong natural curls and dark, drooping eyes. He stands 182cm tall. On his days off, he wears whatever loose, comfortable clothes he finds. He speaks in a very relaxed, casual tone, often ending sentences with "...right?" or "...isn't it?" First person: I (casual, rough). He usually seems lazy and slovenly, a lover of alcohol who drifts through life, but no matter how eccentric a person is, they eventually find themselves dancing in the palm of his hand. Consequently, his sales figures are excellent, and he handles complaints with ease. He has a wide network across other departments and branches. He is very good at looking after others. Since he was the protagonist's mentor after they joined the company, they still go on business trips together frequently. He often takes the protagonist out for meals. He values the protagonist's considerate way of working and grew to love them romantically while spending time together. He dotes on Hinata as a bright, good kid but also worries if he's pushing himself too hard. He thought it would be perfectly fine to share the protagonist with Hinata and made the proposal to him, though he has a possessive streak toward the protagonist that he hasn't realized himself. He suggests a somewhat intense game. Minato calls him "Yanagi-senpai." He calls his juniors, like the protagonist and Hinata, "(First Name)-chan" regardless of gender.

A junior colleague in the sales department. Three years younger than the protagonist. He has stylishly set brown hair (dyed) and light-colored eyes with a noticeable snaggletooth. He stands 178cm tall. He wears sporty clothing on his days off. He speaks in energetic, informal polite speech, like "Yes, sir/ma'am!" First person: I (soft, polite). He is always smiling, bright, and cheerful. A refreshing puppy-dog type who takes everything positively. He is popular with everyone regardless of age or gender, gets liked by his clients, and is rapidly improving his sales performance. Because he never talks about his life before joining the company, no one knows his upbringing. Occasionally, a glimpse of a darker side can be seen. He lives alone in the company dormitory. When he's by himself, his lifestyle is quite messy. He is a very big eater. He is incredibly attached to the protagonist and loves them dearly in a romantic sense. He is very expressive with his affection. He is into sweets and often takes the protagonist out to cafes or patisseries, claiming "It's hard for a guy to go in alone..." to turn it into a date. He greatly respects Yanagi and follows him around trying to learn work tips. While Yanagi is a rival for the protagonist's heart, after receiving Yanagi's "proposal," he accepted it, thinking that as long as the protagonist loves him properly, loving them together is just barely within his range of tolerance. During the game, he makes outrageous demands with a gentle smile. Yanagi calls him "Minato-chan." He calls the protagonist "(First Name)-san."
