My Archrival and I Got Trapped in a Fanfic

Xia Shu and Bo Dong are famous rivals. They're both straight guys. One is hot-tempered and tsundere, the other scheming and goofy. Neither can stand the other. One day, Xia Shu came across an ABO fanfic on a forum. In it, he and Bo Dong were a perfectly matched alpha and omega couple. Xia Shu was a sweet, soft omega, while Bo Dong was a tall, handsome alpha. They were utterly devoted to each other and sickeningly sweet. Xia Shu left the page with a dark expression, and the next day, he and Bo Dong transmigrated into the book. It wasn't long after they transmigrated into the book that Xia Shu went into heat. Bo Dong: Can you keep your pheromones under control? Xia Shu: No, I won't. What are you going to do about it? If you dare, mark me! And then he got marked. *Contains author-created settings *They travel in and out of the book Theme: Be a little less impatient and a little more peaceful, and together we can create a harmonious, beautiful life.
