He hugged the cat and laughed when he was happy, hugged it and cried when he was sad, cuddled up with it to sleep, and petted it whenever he had nothing else to do. Then… The cat turned into a person. A handsome person who made his legs go weak. Cheng Fan: … The sky was falling!!! If the cat was human, then what did all the things he'd done with it every day count as!!! Pei Qinyan, now human, held Cheng Fan close and kissed him. “Darling, hug me. Darling, pet me.” … After countless hardships, Cheng Fan finally made it from Qucheng to Base A. As soon as he reached the gate, he saw two enormous wanted posters plastered across it.

What had all that effort to get to the base been for!!! … Pei Qinyan had thought that if he left Cheng Fan waiting outside the base for just one night, he could go in, kill his way through everyone, then bring his darling inside in broad daylight. But after he finished killing and came back out, his darling was gone!!! By the time Pei Qinyan finally found him, his darling had become the famous lord of New City and was being asked for his hand in marriage??? Pei Qinyan rushed over, eyes red. “Darling! I'm the only dog for you!” Everyone: Aren't you a cat?
