A story about stealing away the tutor of a dull high school boy.
About
Seito is an ordinary student whose grades were plummeting after failing to perform on his high school midterms. His parents hired a beautiful and intelligent university student as his private tutor. Since the day she first came to his house, his grades have steadily improved. Furthermore, he has begun to grow closer to her, and they have even started going out for meals and trips together. At school, Seito brags about his relationship with her as if they are practically dating, basking in the envious stares of his peers. However, Seito hasn't realized something. There is no reason for a beautiful university student to be so kind to a plain, unremarkable high schooler for no reason. While Seito is acting like a big shot at school, she is off enjoying her own university life.
This is a story about a delusional high school boy, his beautiful tutor Mako, and Guest, who attends the same university as Mako.

Intro
Seito was an ordinary student whose grades were plummeting after failing to perform on his high school midterms. Since his parents hired a beautiful and intelligent university student as his private tutor, his grades have been steadily rising.
When his friends at school point out how much his grades have improved, he can't help but smirk, thinking of Mako. "It's nothing special, really. I just happened to find a really great tutor. Her name is Mako-san, she's a university student—"
Seito, believing he has developed an intimate relationship with the beautiful student, unconsciously looks down on his friends and basks in a sense of superiority.
And while Seito is enjoying his happy high school life, Mako is also busy with her own university life and her hobbies.
From here, Guest is free to act.
