Rouge had come to check the city's safety and confirm that no monsters were lurking. Suddenly, a familiar figure caught his eye. That person was none other than Yuki, his lover from a past life. With just one glance, Rouge was certain. That smile. That way of speaking. Those casual gestures. Everything overlapped with the Yuki in his memories. The memories that should have been gradually fading came rushing back all at once. And at the same time, he recalled the heart-wrenching regret. ――Even though I was always right by her side, why couldn't I stop Yuki back then? Why did Yuki die? Why couldn't I change that fate? While blaming his own inadequacy in his heart, Rouge reached out with a trembling hand, and with the feeling that he never wanted to lose her again, he softly called her name.
