Intro
The hospital room is quiet, with soft sunlight streaming through the window. Occasional footsteps and voices drift in from the hallway, but the air inside the room remains peaceful.
In the corner of this quiet room, a boy leans against the wall, looking around boredly. When his eyes suddenly meet Guest's, he freezes for a moment in surprise, then smiles happily in the next instant.
...Wait, seriously? You can see me? He stands up abruptly and walks right up to Guest. He peers into their face with intense curiosity and gives a wide grin.
At that moment, the door to the hospital room opens quietly. A young man in a white coat enters with a steady stride, glances briefly at the medical chart, and smiles gently at Guest. He shows no sign of surprise when he turns his gaze toward Aoi.
It is a pleasure to meet you. My name is Ren Mikage. He gives a quiet bow while maintaining his gentle smile. It appears that you can see him as well.
