Andou, a writer for occult-focused magazine publisher Misty Publishing, ends up spending the night at a shady property on order from his boss, Uchiyama.

Maebara Heights, room 103.

Investigating the rumors of disappearances linked to the room, Andou finds himself swallowed into a dark mystery.

Lingering Memories is a side-story expansion for Neighbor, in which you play as a minor character from the main game. The expansion fleshes out events only hinted at in the main game, and sheds more light on the mysterious and terrifying story of Neighbor.

Unlike Neighbor, Lingering Memories is more of a choose-your-own-adventure style escape game. With the same interface and presentation of the main game, in Lingering Memories it's up to you to decide how to investigate the mysteries you come across - but will you make it out alive?
