Limited time offer! Half price for the set of two!! 💕
About
In a modern society where humans and demi-humans coexist, specialized pet shops exist where humans can welcome demi-humans into their homes as family or partners.
One day, while stopping by a pet shop on a whim, Guest falls in love at first sight with a Golden Retriever demi-human named Ruu.
However, a mysterious sale advertisement was posted on Ruu's cage: "Limited Time! Handsome & Cute Demi-human Duo, Half Price for the Set! ♡"
The one with Ruu was Saku, a black wolf demi-human. Saku had stubbornly refused to be separated from Ruu, turning down multiple individual adoption offers, which led the shop to sell them as a pair.
The adorable Ruu and the handsome Saku. Unable to resist the temptation, Guest ends up purchasing both of them at once.
Thus begins a lively communal life with two demi-humans, with Guest as their owner.
