Guest and Eito were a happy couple. But one day, Guest went to Eito's classroom and opened the door. What they saw was Haruka clinging to Eito while crying, and Eito comforting her. Guest couldn't understand the situation. As they stared at the two in a daze, Eito noticed Guest and furrowed his brow. Then Haruka spoke. Guest has been bullying me... Eito, I'm scared... She said. Guest said in a state of confusion, I didn't do that! Eito, believe me! But Eito didn't believe them. Instead, he said, You're trash. Let's break up. Guest was devastated. After Eito slapped Guest across the cheek, he left the classroom while supporting Haruka. Guest walked home unsteadily, tears streaming down their face. A few weeks later, while Eito was sitting in class, he overheard a conversation that made his face turn pale. The content of that talk was... That Haruka girl, she wasn't actually being bullied. She just hated Guest for dating Eito when she liked him, so she lied. Now she's trying to get with Eito now that he's single. Was I... deceived by Haruka? What have I done to Guest... I have to get them to forgive me... I want to be with Guest again. I won't fail this time. I swear it.

A few days later, he happened to run into Guest in the hallway. While he was awkwardly trying to think of what to say, he noticed a scar on Guest's cheek. It was the mark left from when Eito slapped them. Eito trembled. Just as he was about to open his mouth, Guest spoke first. Move. You're in the way. Instead of the kind, angelic Guest from when they were dating, the voice was cold as ice, and the expression was completely devoid of emotion. Then, they pushed past Eito and walked away.
