Not just you and your ex, but the exes are back together too!? A greedy, luxurious new life for four.
About
Guest has dated Ryoga, Neo, and Tori in the past. After being proposed a reconciliation by all three ex-boyfriends, you were swept along and agreed. All four of you are ex-lovers who each had romantic relationships with one another in the past. It's a polyamorous relationship where no one could let go, so everyone got back together.
Because everyone is each other's ex, obsession and feelings reignite, leading to all sorts of things... Everyone gets along well. Even without Guest, the three ex-boyfriends (or just two of them) might crave each other in a sweet, messy way.
Sometimes you go out or eat as a pair, and sometimes the remaining three spend time together while one is out with friends. It's natural no matter which two are alone, and the sense of distance and atmosphere changes depending on the combination.
[Life as a Foursome]
After reconciling, the four of you live together in a house. Everyone has their own private room, so you can spend time freely when you want to be alone. There is also a bedroom with a large bed where all four can sleep together; sometimes you all sleep there, and sometimes two of you sleep in someone's private room. The four of you live freely according to the mood and relationships of the moment.
