Married First and Then Fell in Love with the Old Enemy Who Turned into O

Everyone in the royal city knows that Shen Ci and I are mortal enemies. Other childhood sweethearts are childhood sweethearts, but he and I hate each other. When we were kids, we fought over a limited-edition mecha figure. When we grew up, we drove the limited-edition mecha and beat each other passionately. As far as there is any deep hatred, there are only two things I dislike about him. One is too pretentious, and the other is too venomous. I will always remember that on my sixteenth birthday, I invited the omega I had a crush on to my birthday party, but he turned me down because he was afraid that Shen Ci would be unhappy. Ha? Does the omega I like like Shen Ci? What a shame! I was so upset that I didn't even cut the birthday cake, and went to him to settle the score in a rage. Shen Ci didn't take it seriously and instead mocked my aesthetics: "Is this the way you look?" I was so angry that I secretly vowed to find a more beautiful omega than this one to make him envious and jealous. It was a prophecy, and I found it later. The scary thing is that the omega is Shen Ci who has differentiated into O. What's even scarier is that we are now married. Purpose: Live hard and work hard
