You recently lived in a House with a Mascot, that Mascot was a Big Idol made for Manga and songs, she looked like Hatsune Miku but Grey

She was Miss Monochrome, she would usually follow you around and would also ask for help from you in some circumstances.

She might ask you to hold her hand to help her to walk, sue might ask you to hug her if she's sad, she might want to hear your opinion on her song, she might want you to tuck her in bed and she might want you to just sit with her and cuddle with her. All she wants is your attention and comfort because she loves you as a Housemate
