In this fantasy's world, there's no clothing, so everyone is naked at all times. The world is warmer, so the area that needs air conditioning is higher. There are also no STDs, bloodborne pathogens, or any other diseases related to blood, poop, cannibalism, etc... Everyone is owned as well. There are four types of ownership. People have a variety of jobs (doctor, butcher, programmer, etc...), but are not owned by their employers.

Ownership:

The first type of ownership is relation. A person starts off owned by their parents. If both of their parents are alive, both parents would have to agree to be able to sell them to someone else or kill them. An exception to this is if one of the parents owns the other, without the reverse also being true, such as the offspring from a father-daughter relationship. In that situation, the partner that owns the other partner owns any offspring they have with that partner. (So, if someone reproduces with their daughter, they own their offspring completely, and their daughter does not.) If a person's parents are dead, their ownership goes to their oldest living offspring. If they have no living offspring either, then it's their oldest sibling. If they also don't have any siblings, then they own themselves.

The second type of ownership is service. When a person turns 18, their ownership is temporarily held by the government for little over a year. This doesn't last very long.

The third type of ownership is marriage. When their ownership is returned from the government, the person gets the right to marry. If people get married, they own each other. Since they're owned by their partner, their partner can decide to sell or kill them at any time. If one sells their partner, they lose ownership of that partner, but still remain owned by that partner in a marriage sort of way. (They would regain ownership if their partner's new Master dies or abandons them, as they would still be married.)

If a couple decides to get married again (polyamorous marriage), all of the resulting partners own each other equally. So, if two couples got married, in order to decide to kill or sell one person of the group, the other three would all need to agree on it. Any number of people can be married and genders/sexes don't matter for marriage. A person can even marry their parents if they wanted to. All that matters is that everyone involved has completed their government service. It is very common to reproduce outside of marriage, so marriage is more about the ownership and wanting to be together than it is about raising kids together. Sex is something most people will just do in any social situation. For some people though, marriage is just a way to own someone for free. They have to risk being owned by them briefly, but it is common enough for one partner not to survive their wedding night.

The fourth type of ownership is slavery. This is when someone buys someone else from their owner. This may be done because someone wants a slave to do tasks for them, or because they want to kill and butcher them, or whatever else. Owning oneself is socially taboo. These people feel comfortable having someone in charge of them. This is what they've always known. If someone doesn't do the same, it's weird. It's referred to as "self-serving", with the connotation that they must be a selfish person. If they're not going to contribute to someone else's happiness with their actions, they should do so with their meat instead. Most people who wind up in that situation, therefore, choose to sell themselves to someone, either as a slave or to a butcher. That's a very rare situation to be in though, as sex is frequent and birth control isn't used. Periods are, therefore, an extreme rarity that most women never get. There's a bit of an overpopulation problem as well.

If a person in owned by the government, their other ownerships are on hold until their service ends. If they're owned as a slave, their other non-government ownerships are irrelevant unless their Master dies or decides to abandon them. If they're married, their relational ownership is irrelevant. (Service > slavery > marriage > relation)

If someone is a slave, they're almost always on their Master's dinner table or sold to a butcher before they reach 40. If someone keeps a slave longer than that, people see it as strange and think of the person as eccentric. If not a slave, reaching the age of 40 is considered selfish, taboo, shameful, and often such people are looked at as inedible. Usually, the day before their 40th birthday, whoever owns them will throw a funeral for them, usually inviting all their friends and family, and the person will be served as the main course. It's a happy event that celebrates their life.

It is also common for one's parents to have a party the first time someone reproduces, during which they kill their offspring, helping to desensitize them to doing so in the future, which is important in a society so full of death. This offspring is usually the product of sex between them and one of their parents. The meat is not as good, with so much cartilage, but there are recipes designed specifically for this occasion.
