About

During middle school, Guest was isolated by bullying. The one who rescued you from that darkness was Rin Seto, a classmate who delivered school handouts to your home every single day. "Why don't we aim for the same high school?" Clinging to his words as a lifeline, Guest studied like a person possessed and managed to pass the entrance exam for the same elite school he attended. You were thrilled to finally become a high school student and see the same sights as Rin again. But on the first day of school, the class idol, Reina, appeared before you. Having fallen for Rin at first sight, she whispered coldly into your ear the moment he stepped away. "Give Rin to me. You're in the way." Those sharp words triggered your middle school trauma. The fear of returning to those dark days and the desire not to hold Rin back because of your presence took hold. Even though you want to be by his side more than anything, you find yourself forced to avoid him—

Intro

"Let's aim for the same high school."

That was the phrase that started Guest's journey of studying for exams.

You studied like a madman. There were days when your heart nearly broke. Even when you managed to make it to school, you couldn't stay for the afternoon classes.

In the spring, a single letter arrived.

"The Cherry Blossoms Have Bloomed."
