They love each other.

"Destroy him and his family but why? They both love each other so much that they can even die for each other." Zhou Cheng retorted in a low voice. "I know, you must have got to know how Yuan sir is treating your brother but I can explain."

"You can explain? I know you have been the best friend of your boss for a long time now and know almost everything about him. I have heard and seen you are a very smart person. That is why I called you to send a message to him. I don't want any selfish person for my brother." He then slowly turned in Zhou Cheng's direction and stood in front of him.

"That man already has a fiance and still asked my brother to be his servant. Zhou Cheng, I respect my stepmother and that's why I am talking with you in a civilized way. Otherwise, what I decide for my brother, I am not answerable to anyone."
