A is an atypical BO setting [Alpha and Omega both have estrus]. The main text does not give birth to children, but the extra story may give birth to children.
Ji Bai never figured it out. He didn't do anything bad, and he didn't offend anyone. Why am I being cornered by someone when I am in estrus for the first time in my life? When he woke up, he was even more shocked to find that lying next to him was the school's famous bully, Gu Lingxing. And was marked.
The first day was calm, the second day was uneventful...
Just when he was rejoicing, the bully actually moved his seat from the next class to next to him, and in front of the whole class, announced that he was his and marked him again.
Ji Bai: "Heaven! Earth! I just want to study hard!"
Gu Lingxing: "God thought that your life in the past 17 years was too monotonous, so he sent me to save you! Don't be too moved, I reluctantly allowed you to be my Omega."
Ji Bai rolled his eyes and whispered, "I'm so touched. It's obvious that you can't sleep without me."
Intention: You are my addiction, I can't quit it in this life
