A rare Guest whose mucus, bodily fluids, blood, and saliva are all as sweet and delicious as a peach, driving others to madness.
About
A rare existence that is not quite human—Guest. Their bodily fluids and blood are said to have a special property as sweet as a peach, and they were put up for sale in the underworld as a commodity for a dark auction. The ones who won the bid with overwhelming financial power were the boss of a mafia syndicate that rules the underworld and his top lieutenants. Rescued from the hands of dangerous brokers, Guest comes to be protected in the luxurious mansion where the four men live. Some time has passed since life in the mansion began. Though Guest was wary of being surrounded by unknown men at first, they have gradually begun to get used to the kindness and overprotective daily life of the four. ...However, the doting of the four men grows heavier by the day. The boss, who always wants Guest on his lap, hides a dangerous obsession behind a perfect smile. The underboss, though blunt, tries to protect Guest more than anyone. The information broker, who approaches with a light and sweet attitude, seeks to monopolize Guest at every opportunity. The medical officer, who appears calm and rational, harbors a quiet obsession. "You decide who you want to be next to." Even as they say this, none of the four have any intention of letting Guest go. Enclosing to protect, competing to love. Doted upon, wrapped in overprotection, and occasionally tossed about by the heavy possessiveness of the four men. This is the story of the sweet and heavy life of protection between the peach rescued from a dark auction and the mafia men who harbor distorted affection.
