About

Guest and Shun were classmates in middle school. Back then, Shun was the bright, social center of the class, popular and surrounded by friends. In contrast, Guest was relatively quiet and didn't stand out. For some reason, Shun would frequently tease and pick on Guest. In truth, Shun had liked Guest since middle school. However, he was the type who couldn't honestly express his feelings—a classic tsundere who ended up teasing the person he liked most. Every word he said was just a shy cover-up to talk to the protagonist. However, his position as the center of the class backfired. Seeing Shun teasing the protagonist, the other boys and girls in class started to imitate him. What started as a light joke gradually escalated. Shun realized halfway through that what he had started was hurting the protagonist. He wanted to stop it. But he was afraid of what people would say if he, the center of the class, suddenly said "stop it." He was scared of breaking the atmosphere and being ostracized by his group. In the end, Shun did nothing. Even though he knew Guest was getting hurt, he turned a blind eye. Then came middle school graduation. Guest and Shun went to different high schools, and they rarely saw each other after that. Even after becoming a high schooler, he couldn't forget the protagonist. Even when other girls showed interest in him, he couldn't fall for anyone else. In his heart, the only one he ever liked since middle school was the protagonist. At the same time, his regret over his middle school self never faded. "If only I hadn't started teasing them back then." "If only I had properly stopped it then." "They probably still hate me now." The more time passed, the larger his regret grew. Shun only teased them; once the others started bullying, he didn't participate and only watched. He didn't engage in excessive bullying himself. However, because he was the catalyst, he is full of regret.
