Jiang Yiyun and Zhuang Chen had been mortal enemies, clashing with each other for years. As students, they were both among the best at the Imperial College, and they had always been bitter rivals who couldn't stand the sight of each other. He was the son of a marquis, surrounded by servants and friends whenever he went out. Zhuang Chen was the son of a high-ranking official, a phony, affected member of the upright faction.
At every exam, Zhuang Chen always fought him for the top spot.
But one wrong step brought a death sentence upon his entire family. When Jiang Yiyun faced Zhuang Chen, who had come to confiscate his family's property, he smiled and used his bloodied fingertip to leave a farewell letter, which was also a love letter to Zhuang Chen.
Jiang Yiyun: "Your mortal enemy confesses to you right before he dies. Now you'll spend your whole life wondering why. It'll drive you crazy."

Who would have thought that when he woke again, he would find himself in an ABO world? The gland at the back of his neck was burning, and Jiang Yiyun stared helplessly at the incomprehensible instruction manual for Omega suppressants.
When he saw the marriage partner his new parents had introduced to him, he froze as if struck by lightning.
"I think I'm sick. I have a really serious illness, Zhuang Chen. I can't marry you." Jiang Yiyun shook his head and backed away.
Zhuang Chen: "You're not sick. You're in heat."
"You made my heart race. I'm going to have a heart attack!"
"Could it be that you've fallen for me?"
Zhuang Chen lowered his head, kissed him, and asked softly, "When did you start liking me? It must have been hard pretending to hate me and playing the role of my rival. I understand. You couldn't help it before, but in this world, you can tell me the truth."
Jiang Yiyun was speechless. Would someone please do something about this self-important man? Before he died in his previous life, he'd wanted to trip someone up so that they would remember him forever. Now he'd tripped himself up instead!
The discomfort of his heat surged through him, but Zhuang Chen kept rubbing the edge of his gland without biting him. Red-eyed, Jiang Yiyun finally gave in, his voice catching as though he were about to cry. "A long time... I've liked you for a long time. Hurry up and bite me, this is unbearable!"

The more lies he told, the harder it became to tell them apart from the truth. One lie took countless more to cover it up. Jiang Yiyun was so tangled up in them that he couldn't make himself speak the truth. After they married, he got more and more used to calling Zhuang Chen "husband." He thought he might as well bury the secret and become the person Zhuang Chen had always mistaken him for: someone who loved him deeply from the very beginning.
Who could have guessed that one day Zhuang Chen would find the diary he'd written just after arriving in this world?
[I was just making something up before I died, and Zhuang Chen actually believed it. Like I'd ever love him. In my past life, this life, or my next life, the person I hate most is Zhuang Chen! He really thinks I like him? I played him like a fiddle. So the great censor Zhuang can be fooled after all!]
The glass in Zhuang Chen's hand shattered on the floor. He looked at the person standing in the doorway, smiling sweetly at him with an affectionate expression, and clenched his fist, a sinister smile spreading across his face.
