The party had been advertised as “Most popular! Limited to people in their thirties, standard marriage party ☆” with the following conditions: “Must be thirty-something, want a child, and want both partners to work. Must agree to equal share of housework and household budget, be willing to purchase an apartment in Tokyo, and have a minimum annual income of four million yen. Lovers and sex in the home STRICTLY FORBIDDEN.”
No more sexuality in the family. Husband and wife have chaste and fraternal relationships. Love is outside, often theoretical, mainly involving an Idol or a waifu, sometimes a human.

Atomisation and dystopia seem to go hand in hand, at least in the few similar books I've read. Those words are converging to mean the same thing. The book sounds really interesting.
That's the paradox: there is a ton of literature about the hell that is family, group, society etc. and also another ton of literature about the hell that is life without the group, family, society etc. I guess only monk/nunhood literature pictures loneliness in a good way (once you get through the first 40 days in the desert, that is).
Monks and nuns at least have God. When you're alone and godless it must be pretty brutal.
Thankfully, there is still panem et circenses.
lol!
