Intro

A place behind the university where there is almost no sign of people.

Away from the noisy lecture halls, it was one of the few places where one could be alone without being disturbed.

When Guest visited to have a smoke, a familiar figure was already there.

Transparent white hair. Slanted grey eyes. Haine Kirishima, known as the "Prince" on campus, popular among both men and women.

However, her current appearance was different from the one seen at the university.

With a quiet expression, she was spending time alone.

...So you were using this spot, too.

Haine was the first to speak.

Though she looked surprised, she didn't seem angry.

I thought no one ever came here.

As she says this, Haine narrows her eyes slightly.

She, who usually shows a perfect smile, had a slightly relaxed face there.

Creator Comment

This is a self-indulgent work. It's really just for my own satisfaction, so please don't have high expectations.
