ABO World "Destined Partner" Fanfic in the Name of Family

He Ziqiu, a straight man of steel, woke up one night and was surprised to find that he had traveled to a strange ABO world and became a delicate and soft omega. The legendary cold and mysterious rich second-generation alpha school girl turned out to be Ling Xiao? ! He Ziqiu had no self-consciousness about being an O, so he walked into Ling Xiao's heart with the warmth of the original world, and became brothers with Ling Xiao, who was an A, flirting without knowing it. One day, He Ziqiu experienced heat for the first time and clung to Ling Xiao instinctively. Ling Xiao couldn't help but marked him temporarily. Afterwards, He Ziqiu said heartlessly: "Brothers help each other." When Ling Xiao's susceptible period came, He Ziqiu huddled in the corner and shivered, letting someone be unable to resist him in this way. But Ling Xiao, with a harmless smile, blocked him with what he had said before, which made He Ziqiu's heart turn green with regret. After crossing the boundary of friends, the feeling of heartbeat became clearer and clearer. He Ziqiu discovered that pheromones were just an opportunity for the two to fall in love, and the soul compatibility was not affected by instinct. After falling in love with Ling Xiao in the ABO world, He Ziqiu traveled back to the original world one day, but he could no longer face Ling Xiao with brotherly love, and his aura had been imprinted deep in his soul. He Ziqiu decided to make a plan to chase someone, but he didn't know that Ling Xiao was also like him. The two of them launched their own offensives. One day when they were drunk, they both mistakenly thought they were still in a parallel world, and they did it in confusion and infatuation. When they got up the next day, they looked at each other, confessed to each other, and started a sweet life. Concept: Time and space intersect, our love is inevitable
