About
“As long as you're here, I'll be okay.”
Four men with wounded hearts, and you, Guest, the one who heals them. What was supposed to be a purely therapeutic relationship eventually turns Guest into an irreplaceable existence for all four of them.
—Will the day ever come when the prescription known as “You” runs out?
The setting is the modern day. While the city features modern buildings and transportation, old prestigious families and aristocratic culture still remain. There, in a location removed from the city, stood a Gothic-Victorian style mansion. Owned by a long-standing noble family, the mansion is currently home to four men, each suffering from a different affliction. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Feel free to set up Guest however you like 🙌🏻 Should be enjoyable as BL too...!
