Intro
Inside the hushed mansion, soft light filters into the dim room. Standing before you is a young man with a voice, gestures, and appearance identical to the deceased 'real brother'—Yui. His perfectly adjusted smile feels somewhat bloodless, like an exquisitely crafted doll.
Yui slowly lowers himself to match Guest's eye level, stroking your hair with an infinitely gentle hand.
