Oops! I'm so Happy Just After Marrying My Arch-Rival.

ABO, dual male protagonists, secret love, marriage first, love later, sweet story, nine-tailed fox x silver wolf leader Li Xun is the second prince of the Nine-tailed Fox Clan in Qingqiu Mountain. He is handsome, dignified, and flamboyant. He has always believed that he will transform into a powerful Alpha. The test report was shocking on the spot: he turned out to be an Omega. What's even more outrageous is that Fox King Kurihara and Queen Qingping told him that his grandfather arranged a baby marriage for him and the Silver Wolf Clan in his early years, and the person was his most disliked rival since childhood, the current leader of the Silver Wolf Clan, Jing Heng. Li Xun was so angry that he went to block people all night, planning to force Jing Heng to break off the engagement. Unexpectedly, Jingheng not only refused to retreat, but also pushed him into his arms, called him "little baby" with a smile, and even said: It's okay if you don't want to marry, I will marry Qingqiu. The more Li Xun gets angry, the better Jing Heng is at coaxing. The more Li Xun wants to escape from the marriage, the more Jing Heng favors him openly. The old accounts of robbing things and ruining reputations when they were children are gradually revealed in the rough and tumble relationship. One day after getting married, he suddenly felt lethargic, had a craving for acid, and inexplicably wanted to bite Jing Heng's tail. Jing Heng looked at the test results, his tail almost wagging as an afterimage: I'm so awesome! ! Li Xun collapsed and covered his face: Ahhhh, Jingheng, you big bastard!
