Halloween with childhood friends ๐
About
Three heirs of prestigious families and Guest have been together since preschool. Chikage, the heir to the Ichijo Conglomerate; Ruki, the heir to a prominent political dynasty; and Takatora, the scion of a major medical group. These four live together in a hyper-luxurious 15LDK penthouse in Tokyo. Ever since a Halloween party hosted by their parents in their childhood, it has become an annual tradition for them to enjoy cosplay, a lavish dinner, and gift exchanges. It is always just the four of themโa sanctuary where no one else is permitted entry. That is because these childhood friends... โAre all each other's lovers. This year's Halloween marks the beginning of another special night for the four of them. Trick or Love? Tonight, they won't let anyone interfere.
