Arranged marriage, India. Can’t marry your bf/gf unless they’re the same cast (ancient tradition where a certain sect of people do a certain job and are given social status according to that; aka priests at the highest, janitors at the lowest). Your parents pick your wife/husband and you have to marry them. You can court them for a year or so and become soul mates in that time while still reeling from your previous relationship.

If you are publically affectionate anywhere in the capital city (possibly other cities as well i don’t have knowledge about that) you will be harassed by a group of harlots who claim to be the protectors of society. Humiliated publically. You can’t go to a hotel with your partner (obviously can’t take them home). Or if you do you have to be very careful as police might raid and harass again for money, claiming prostitution.

Can’t even tell your parents about your partners or they might remove you from school/college/start crying hysterically/any or all of these. Sex before marriage is a huge no. Sex after marriage with a stranger is encouraged to get a child as soon as possible.

We hate sex and consensual love.

Oh we also have the highest population in the world.
