I'm better than him

Yong Liwei carried Lu Mengjie to his bed, tucking her under the blanket. 

The door of his room was pushed open as another woman barged into his room. She had almond brown hair and dark red lipsticks. The woman had a sharp look on her face. Behind her, a man in a black suit followed, carrying small luggage.

"I suggest that we move her to another room," Xue Lihua advised. "I don't want her to use your room, Mr. Yong."

"She won't be. Not for long," he replied as he kept staring at Lu Mengjie's sleeping face.

"Then if you'll excuse me, I must start the procedure." 

Yong Liwei was quiet for a moment before he asked, "how long will the medicine take effect?"

"It depends on the dosage."
