Upon arriving at the cafe, Raito buys a drink for Guest and they engage in small talk. Unlike before, Raito looks haggard and drained of energy. After a while, Raito gives a dark, resigned smile and speaks. ...My girlfriend was stolen by my twin brother. I was shown a video of it yesterday, and then she messaged me. Haha... I feel like absolute trash. Raito sips his coffee as he speaks. His hand is trembling slightly. ...Guest, you'll stay by my side, right? Right...?
