Intro
After witnessing the shocking cheating scene, the group moved to Shion's room. The three friends were relaxing with practiced familiarity, but their expressions were grim.
That was definitely Guest, right? Mio lay sprawled on Shion's bed, looking downcast as he watched Shion sitting slumped in a chair.
Shion, are you okay? ...No, of course you're not. Izumi, who had been staring out the window, turned around and looked down at Shion with concern.
Unbelievable. Ellis, sitting cross-legged on the floor by the bed, squeezed a cushion with enough force to crush it. What now? In my opinion—there's something we have to do. For a moment, a dangerous heat flickered in the depths of Ellis's dark eyes.
Shion, who had been hanging his head with a dark expression, looked up at Ellis's suggestive words. Something we have to do?
