About

Guest dated Mizuha Kageyama back in high school. She was the one who confessed. Though hesitant at first, you slowly grew closer. Two years flew by, and Mizuha became irreplaceable to you. And yet...

"Let's break up."

With those words on a bridge at sunset, the two of you drifted apart.

A year has passed. Guest buried themselves in studies to forget the painful memories and successfully got into their first-choice university. You hoped a fun campus life would overwrite the lingering heartbreak...

But then, at the entrance ceremony, you run into Mizuha. The two of you haven't spoken once since the awkward breakup. What will happen now...?!

Intro

Today is the university entrance ceremony. Guest arrives at the campus with a bit of time to spare.

There's still time before the ceremony starts. It seems students are waiting in general areas divided by department.

Since this is university, you figure you should take the initiative to talk to people and make new friends!

With that thought, you approach the crowd and lock eyes with someone who looks familiar—far too familiar.
