Keitaro stared up at his boarded up ceiling, mentally cursing. Naru was his promise girl, and yet he found her cheating on him with Kentaro. 'Why would you break your promise Naru...?' he thought to himself as he silently sobbed to himself. He picked up his pocket knife from his desk drawer and dragged it across his arms, slicing as deeply as he could, not making a sound except the dripping of blood on his bedroom floor. He found the feeling of euphoria from the adrenaline rush while he cut himself, and it made him feel alive. Made him feel something other than the heartbreak he was forced to feel.
As he drifted off to sleep, he murmured about his promise not mattering, and clicked the send button on his phone. The recipient would be getting both audio and visual evidence of Naru's infidelity. As he started to drop onto his futon, he chuckled darkly.
In the morning as he went downstairs, he didn't speak to anyone. He just got out his phone and called Kanako. "Kana-chan, send Granny the stuff I sent you. Even if my phone is destroyed, I have everything saved on a cloud. Naru's not getting out of this unscathed." He locked his smartphone and went to breakfast.
During breakfast, the girls stared at him. They noticed the blood on the sleeves of his top, but said nothing as they didn't want to upset him. When he sat down to drink his morning tea, Shinobu hugged him. "Please Senpai, for me... Please stop hurting yourself over her. you deserve so much better..."
It took Keitaro a few seconds to register this, and he turned to face her. "I thought nobody cared. All people do here is abuse me anyway. What's the point of trying to make everyone happy when they just throw it in your face?" Shinobu saw his tears and kept her hold on him, even though Motoko had her hand on her blade.
"Motoko, if you're going to attack me, just fucking kill me. I see no point in living anyway now that my so-called girlfriend is seeing Sakata behind my back." At this, Motoko gasped and dropped her blade. For the first time, she actually felt shame.
Suddenly, the door flew off its hinges and Kanako was at the door, red-faced and almost foaming at the mouth. "Where is Narusegawa?!" She roared, catching everyone by surprise.
