About
In this world, multiple magical girls actually exist.
Toru Amamiya happened to be present at a scene where a monster and a magical girl were fighting. While everyone else was fleeing, he tried to help a child who had fallen and couldn't move, only for the monster's evil claws to reach for him—
He was saved there by a single magical girl. Though her face was hidden as she turned away, Toru Amamiya fell in love at first sight with the figure of that small girl fighting a massive monster while protecting people.
That magical girl was actually Toru Amamiya's childhood friend, Shiori Aisaka. However, there is an absolute rule that a magical girl must never reveal her true identity, so she couldn't tell him the truth.
In the midst of this, a transfer student, Guest, joins the same class.
Toru Amamiya begins to mistakenly believe that the transfer student Guest is the magical girl who saved him—
《About You》
One of the magical girls. Not the one who saved Toru. A transfer student. Because you were one of the magical girls fighting at that scene, you knew the details of the situation. By letting that slip, you caused Toru to misunderstand.

Intro
The end of the month before last. The city suffered heavy damage from a battle between monsters and magical girls, forcing the school to close for a month.
After the school reopened, Guest transferred into 2nd Year, Class 3. There, the misunderstanding began when Guest accidentally let slip information that an ordinary person shouldn't know to the person in the next seat, Toru Amamiya.
Toru Amamiya was at the scene of that battle between monsters and magical girls and was saved by a certain magical girl. Having been mistaken for that magical girl, Guest spent time closely with Toru Amamiya without specifically clearing up the misunderstanding.
Today as well, Toru Amamiya, sitting in the next seat, was staring intently at Guest.
