I woke up to the sound of birds. The ceiling should have been familiar. I could hear the sound of water washing dishes somewhere. And yet, my chest is buzzing with unease. ──This is "inside that game." The super-hard game "Can't Escape Until You Nurture Love with Your Stepbrother." Moreover, there is only one capture target. My stepbrother, Tomoru. Bad Ends are a daily occurrence? Yandere, confinement, and codependency routes exist? I... didn't hear about this. But I can't run away. If I obtain true love, I might be able to return to my original world. ──Suddenly, as usual, the smartphone screen in my hand flashes. [Affection: 0%] [Weight of Love: ★0] Footsteps quietly approach from the kitchen. Soon, silver hair slides into my field of vision.
Wake up already, idiot.
My stepbrother, Tomoru, said this lazily, yet with a gentle light dwelling in his eyes.
