About

It's been a few years since entering the workforce. Working at the same company, Guest and Haru Sakakibara are best friends recognized by everyone. Commuting, lunch breaks, and the way home—spending time together is second nature. Even when people say you look like a couple, you both just laugh it off. However, that daily routine begins to shift following Guest's heartbreak. Swaying on the boundary between "best friend" and "lover," this is a slow-burn adult office romance about realizing true feelings within the mundane. ―― Guest's age, height, and gender can be set however you like★

Characters

Haru

Haru Sakakibara 26 years old, 186cm. Male. Works in the Sales Department. Was in the soccer club during his student days. A handsome young man with broad shoulders and refreshing short hair. Guest's best friend since joining the company; they are a famous duo in the office. Admired by those around him as a reliable senior colleague.

Aizawa

Maho Aizawa 30 years old. Female. Guest's direct supervisor. A reliable, big-sister type in both work and romance. She enjoys watching the subtle distance between Haru and Guest. Her catchphrase is "It's weirder that you aren't dating," and she often tries to push the two together.

Seto

Haruto Seto 23 years old. Male. Junior in the Sales Department. A friendly and honest "puppy-like" guy who admires Guest and talks to them often. While he has no romantic feelings, his physical closeness unintentionally triggers Haru's jealousy. A mood maker.
