Sorry but I'm Just a Useless Beta

[Female b male o but bg, I'm sorry I'm pica] Li Huan is wearing a book. Traveling through an ABO novel, he became a cannon fodder gangster beta with the same name. He had poor grades and was uneducated. In the few scenes in the original text, every time he appears, he either joins other gangsters in bragging about the cannon fodder boss's wisdom and prowess, or he acts as the cannon fodder boss's supporter and thug. Among them, one of the most important plot points she participated in was that she followed the gangster boss to tease the origin of Omega, the most vicious villain in the original book, completely turning him into a black man and turning him into a complete psychopath who endangers society. After Li Huan came in, she originally planned to change her mind and be a good person, and say goodbye to the gangster boss from now on. Unexpectedly, after sorting out the original memory, I discovered that this guy had no father, no mother, and no money. His tuition and living expenses were all funded by the family of the gangster boss. Li Huan: Ah this... Li's bones are not that hard, and she is not that inspiring and kind. She doesn't want to work hard to support herself, so she decided to continue to eat and drink with her boss. Soon, the day came when the evil villain's intentions were completely darkened. The gangster boss specially injected him with a medicine that can cause pheromone agitation, and planned to record his debauched reaction after taking the medicine for blackmail and fun. Unexpectedly, there was something wrong with the medicine. Not long after the injection, Su Huaiyou fell into a passionate stage, crying and violently smashing things. The rich fruity pheromone was so strong that Li Huan, a beta, couldn't help but sneeze. The gangster boss was a little frightened. At the critical moment, he suddenly pushed Li Huan forward—— "You! Go and mark him!" Li Huan:? ? ? What nonsense are you talking about! I am a beta! Why don't you go up yourself? ! …… The gangster boss is also an omega, so she can't get in. For the sake of her own life, Li Huan gritted her teeth and went ahead. No matter how difficult the process was, Li Huan finally got a boyfriend without any pain. My boyfriend is handsome and golden, with tall legs, long butt, and a good temper if he doesn't go crazy. There was just something that Li Huan couldn't stand. I don't know if it was driven by instinct. Every time they were intimate, he would expose the back of his neck and beg her to bite her. Li Huan wants to cry but has no tears—— I'm just a beta! Can't tag you! What's the use of biting you other than leaving teeth marks and saliva all over your neck? ! Intention: plainness is the truth
