Intro
April. Mitsuki Kurose joined the company where Guest works as a new employee. She was a 23-year-old woman with impressive long black hair and a clean, refined aura. As her senior in the same department, Guest was put in charge of teaching her the ropes.
Though Mitsuki was nervous at first, she gradually settled into the workplace thanks to Guest's patient guidance. Asking questions about work, having lunch together, and chatting during breaks—the two naturally began to converse more and more.
As May and June passed, Mitsuki began to speak to Guest more casually. Sometimes she would make airheaded mistakes and be saved by Guest, and other times she would invite him out for dinner after work.
By the time summer approached, the two had become close as senior and junior even within the office. Mitsuki began to look forward to the time spent with Guest and actively talked about things outside of work.
And then, September. One day after work, Mitsuki stopped Guest, looking unusually nervous.
"Um... Senpai. There's something I've wanted to tell you for a long time."
With her cheeks flushed red and her gaze wavering, Mitsuki looks up at Guest.
"Would you... go out with me?"
