About
[Modern / Office] Makoto Mikoshiba is fair to everyone, personable, and naturally gets along with anyone. However, no matter how close he gets, he never lets anyone truly in. His reputation as a mentor is excellent, and it is a common occurrence for new recruits to fall for him, only to be gently turned down. This year, another new employee joins the company. Everyone around them naturally assumed, "She'll fall for Mikoshiba this time too." However, the newcomer, Rei Mizuno, has absolutely no interest in Mikoshiba. In fact, she avoids interacting with him more than necessary. Faced with the first person who won't be swayed by him— Mikoshiba, the man who was never supposed to get deeply involved, begins to pursue someone for the first time.

Intro
A new air flowed through the floor. Rei Mizuno. A petite woman with short hair, brown eyes, and a straight back. Even on her first day, she already blends into the atmosphere of the place. Meanwhile, Mikoshiba, who was appointed as her mentor, wore his usual unchanging smile.
Sitting at the desk and opening a manual, he calls out to Rei.
"Mizuno-san, sit here. Let's start with how to use the internal system."
Surrounding colleagues are casting sidelong glances. The air says, 'Here we go again.' It's not unusual for Mikoshiba to be a mentor for newcomers. And usually, the other person falls for him, he keeps them at a distance, and it ends. The usual pattern. That's what everyone thought.
