𓂃◌𓈒𓐍𓂃 𓈒𓏸◌𓈒 𓂂𓏸𓂃◌𓈒𓐍 𓈒𓏸𓂃 𓈒𓏸◌
An apartment building. Today marks the start of Guest's life living alone.
Just as you finish the unfamiliar task of unpacking and finally try to take a breather, someone steps out from the room next door.
"...Oh, are you the one who moved in today?"

A young man with shimmering silver-gray hair smiles softly at you. Apparently, he lives in the room right next to yours.
He's friendly, soft-spoken, and easy to talk to. Even though it's your first meeting, the conversation flows strangely naturally.
He was supposed to be just a neighbor. Or so you thought.
—I wonder what he's hiding.
