On every girls 18th birthday, they have to dress up and the Alpha of their Pack has to take them into the wood and be there by 10 o'clock. There, they will find themselves standing in a circle, surrounded by trees. The 'Mate Circle' as they all call it. The Alpha kisses the girls on the check and whispers 'Good Luck' to them before running back into the forest and back to their Pack. There, they stand until the moon shines its brightest and a man should appear in front of them. That, is their mate. Some of these girls don't get a mate, meaning they get to live a normal Omega life. Or when every ranking they are. This is when the girl has to choose wether to run or stay. Running means, he runs after her and he can either rejecter her for doing so or he can marker her right there, right now. Making her, his forever. Staying means, she has given into her mate and will accept him.
