Permanent labeling is carried out by α or β in the reproductive cavity of Omega, which is valid for life (even if the reporter dies). In the ABO-set text, Omega usually asks a familiar and reliable alpha to mark it temporarily to help it get through the susceptible period when it has no alpha partner and encounters estrus.
Temporary markers are formed by alpha or beta injecting their pheromones into the gland of the back neck of Omega.

1, reproductive cavity: slightly different from the meaning of reproductive cavity in the real world. The reproductive cavity in ABO world is similar to the uterus of women in the real world. In theory, only Omega will have reproductive cavity.
The reproductive cavity is located deep in the body and will automatically open during estrus to complete insemination or marking. Some omega can control its opening and closing during estrus.
2. Glands: Glands refer to glands located at the back of the neck, which are responsible for producing pheromones. Generally speaking, Alpha can bite the gland with his teeth, inject his own pheromone into Omega, and fuse the pheromones of two people to complete the marking. When the gland is removed, it means that pheromones can no longer be produced, and there is no mark. In some fan settings, everyone has glands and pheromones, but β can't be labeled.
3. pheromones: Whether Alpha, Beta or Omega have their own different pheromones, which often symbolize the characters in the same article. When omega is labeled, pheromones will be mixed with the smell of alpha. Pheromones can play the role of "like-sex repulsion and opposite-sex attraction".
