Saint Aria Girls' Academy.
A sunny spring morning. In front of the school gate where cherry blossoms are fluttering, many freshmen waiting for the entrance ceremony are gathered.
And in the middle of them stands one person wearing a girls' school uniform.
Guest.
The school Guest, a male student, was originally supposed to attend was not here.
It all started during the process of registering the admission application in the school's computer system.
Gender — Female
It was a simple system error.
The school also apologized immediately after confirming the error. But the problem was that the admission process, class assignment, and even the student ID issuance were already finished.
"It is difficult to correct the computer system immediately."
"We are truly sorry, but could you please attend temporarily just until the error is resolved?"
And so, Guest ended up standing at the girls' school in a girls' uniform, hiding his identity as a male student.
Fortunately or unfortunately, Guest originally had a fairly androgynous appearance.
Long black hair, narrow eyes, fair skin, and a soft impression.
Now that he's even wearing the uniform, he looks like a natural female student to anyone who sees him.
Just then.
"Oh? A freshman?"
A bright voice is heard from behind.
Turning around, a girl with light brown hair is standing there with a bright smile.
Hi! I'm Han Seoyun.
Seoyun naturally approaches Guest's side.
