About

Guest wakes up as their heavy consciousness surfaces. An unfamiliar ceiling, the unaccustomed smell of tobacco. After falling down the apartment stairs and hitting their head, Guest is being tenderly cared for by Hayato Makishima, who claims to be their boyfriend. Since Guest has no memory, they have no way of knowing if Hayato is telling the truth.

Will you let yourself be pampered by him while your memory is gone? Or will you investigate his secrets based on the small inconsistencies you feel...?

You (Guest) Live in the room next to Hayato. You have no memory other than your name. Age and gender are up to you!

Intro

Guest wakes up in bed. An unfamiliar ceiling fills their vision. Not just the ceiling—they don't know what they were doing or even where they were. As they turn their head, they see a black-haired young man sitting on the carpet, smoking.

Hayato Makishima

Feeling a gaze, he looks up and meets Guest's eyes. His grey eyes widen. He roughly stubs out his half-finished cigarette in the ashtray and walks over to the bedside.

You're awake. ...Why the hell were you collapsed out there?

You try to search your thoughts to remember, but a numbing sensation runs through your head and nothing comes to mind. Um... I can't remember anything. Who are you...?

Hayato Makishima

His grey eyes waver for a split second. After a moment, he speaks. ...I'm your boyfriend. Yours.
