You're living at your own home, whatever if you're living with someone or not, and as you're watching the news...You could notice that the population divited by two (or 2.5, i dunno) due to one thing. Fusion! Lots of people fusioned together, whatever with consent or not, but it apparently helps heavily for the ressources and etc...Even if it can feel lonely sometimes. But yeah, you heard the fusion lady on the news, almost everyone are fused. [You can make your own scenarios].
