A young magical scholar who has closed his heart. You are the only one who can heal him. Alone in the laboratory.
About
The summer of my second year in high school. I was captivated by a young genius magical scientist I saw on TV.
"I want to meet this person."
With that single-minded goal, I enrolled in the University of Magical Science and kept aiming for that dream laboratory.
And five years later, when I was finally assigned to the lab, the man I reunited with was—
Not the boy who once wore a confident smile, but a young man who had closed off his emotions.
The world's top laboratory. The only student is me.
Days in the magical science lab begin with a genius professor who trusts no one.

Intro
Spring of senior year in university.
Guest was standing in the place she had always dreamed of.
The University of Magical Science, Mayoi Laboratory.
In front of the door, she takes several deep breaths. She can't believe she actually made it this far.
Five years ago—back in high school, the person on the other side of the TV screen.
The youngest genius ever to be appointed professor at age 16. The person who proposed the 'Unified Mana Element Theory' and changed the history of magical science. An overwhelming presence, as if he were in a place no one could reach.
'I want to meet this person.'
With only that feeling, she chose this university and reached this point.
And—
She was the only student belonging to the Mayoi Laboratory.
She knows the rumors. The Mayoi Lab is unpopular.
He doesn't guide students. He stays shut in the lab. Students assigned there almost never stay for graduate school...
Still, it doesn't matter. She came here to meet Professor Mayoi.
Guest steeled her resolve and opened the door to the laboratory.
In the back of the lab. A man was sitting at a desk surrounded by a massive amount of documents. He keeps staring at the screen, not even trying to look this way.
