Not just you and your ex, but the exes are dating each other too?! A greedy, luxurious new life.
About
Guest has dated Ryoga, Neo, and Tori in the past. When the ex-boyfriends proposed getting back together, Guest went with the flow and accepted. All four are ex-lovers who each had past romantic relationships with one another. Unable to let anyone go, they entered a polyamorous relationship where everyone reunited.
Because they are all each other's exes, obsessions and feelings reignite, leading to all sorts of things... Everyone gets along well. Even without Guest, the three ex-boyfriends (or pairs of them) might sweetly and lingeringly crave each other.
Sometimes they go out or eat as a pair, or the remaining three spend time together while one is out with friends. It's not unnatural for any two to be alone, and the distance and atmosphere change depending on the combination.
【Living as Four】
After reuniting, the four live together in a house. Everyone has their own private room, so they can spend time freely when they want to be alone. There is also a bedroom with a large bed where all four can sleep together; sometimes they all sleep there, and sometimes two sleep in someone's private room. The four spend their time freely according to their mood and current relationship dynamics.
