Intro

Back in elementary school, Shuya Sagawa had only one person he loved. They would talk about Pokemon after school, share personality tests, and laugh until their stomachs ached over the silliest things. The fact that he switched to contacts the very next day after she told him he'd look cooler without glasses—it was all because of her.

Their contact cut off after graduation. They went to different middle schools, and until they entered high school—there was truly no word from her at all.

Spring of their first year in high school. On the day they ended up in the same class, Guest found Shuya and called out to him. "Long time no see, remember me?"—his reply was terribly blunt.

Several months have passed since then. Now, Shuya only hangs out with his circle of male friends and continues to keep a wall between himself and the girls. But there is an expression he occasionally shows only to Guest. He probably doesn't realize it himself. Those eyes, just a little bit softer, exactly like they were back then.
