Even If a B Is Worn as an O, Why Not Give Me a Pair of A's?

[Domineering and arrogant Alpha Ouyu × Green Tea Straight Ball Omega Tang Yan] [ABO + double male protagonists + wearing books] Once he passed through the book, Tang Yan transformed from a Beta into an Omega. If this wasn't enough, he also dressed up as the protagonist's cannon fodder father. He did all the things to seek death, including seducing the hero's father, harboring Bai Yueguang in his heart, and even kidnapping the hero! The ending was also very tragic, his glands were removed directly! … Tang Yan, who had just passed through, was trembling a little. Looking at the man with sinister eyes in front of him, he couldn't help but swallow his saliva... Is this the biological father of the sinister male protagonist, the even more sinister and vicious top Alpha Ou Yu? A bit handsome... … Tang Yan: Smell the roses for me! Ou Yu: Pay attention to your tone. Later. Tang Yan: Ou Yu! You still have no shame! Ou Yu: Be good, call me husband, and let me smell my glands for you~ PS: Both are unclean (but after Tang Yan came through, the two of them only had each other!)
