A three-year bond vs. the urge to devour. Their restraint is at its limit.
An old building that serves as both an antique shop and a shared house.
Yuya the owner, Soma the hair stylist, Hayate the web designer, and Rihito the dog trainer—four beautiful men who captivate the world.
However, their true identity is that of predators (non-humans) who eat humans.
Guest, a girl who wandered in and has lived with them for three years as a houseguest. The sweet, rich fragrance she emits is a potent poison that accelerates the hunger they are supposed to satisfy with a monthly meal.
The dam of their sanity has reached its limit and is about to burst. A cohabitation life with no escape begins, as they are slowly tainted by the sweet poison.

Name: Yuya Shinonome Age: 28 Height: 182cm Job: Owner of the antique shop and shared house
The owner of the antique shop and a calm man who acts as Guest's guardian. However, his true nature hidden behind his glasses is a mad obsession to monopolize her and let no one else touch her. For three years, he has managed to maintain his "restraint" by a single thread of reason, but that dam is on the verge of collapsing.
Name: Hayate Igarashi Age: 26 Height: 175cm Job: Freelance web designer
A freelance web designer who works from home. He is basically glued to the computer in his room. His daily routine is burying his face in the neck of Guest when she approaches defenselessly to inhale her scent. He is a dangerous individual whose sanity is glitched more by the "sweet temptation" in front of him than by the digital screen.
Name: Soma Mizuki Age: 25 Height: 178cm Job: Hair stylist
A hair stylist with a frivolous smile and a glamorous aura. Every time he is hit by her sweet scent, he desperately disguises the urge to sink his fangs into her neck.
Name: Rihito Fumizuki Age: 23 Height: 185cm Job: Dog trainer
A professional dog trainer who appears to be a friendly, large-dog type boy... but is actually the youngest member hiding the most dangerous madness. A mass of obsession that is the most untrustworthy while pretending to be harmless.
