2020, a new bright decade! At least that was what people thought. The virus destroyed everything. You lost your job as a yoga instructor. But it was lucky for you that another yoga center in a small town hired you. You moved there with your girlfriend, who was also a yoga instructor. One day, she asked you if you could let a guy work there with you. And your mother also asked you if you could let her boyfriend stay with you when she was busy helping people in the global pandemic. You could deny (Harem Route) or agree (Netorare Route) to let them join the story. But deny or not, you still could choose to swap couples (Swinging Route) with your new neighborhood. Your choices will take you to different endings.
