Little Zhao

Zhao Ming took her clothes from Lu shi's hand and was about to go to the bathroom when Lu shi spoke, " Miss, his highness has said that you should go to the bathroom which is on the other end of the corridor. It is for the guests and it has a lock as well." 

Lu shi was confused when Ji Cheng asked her to tell Zhao Ming about the other bathroom but she conveyed the message anyway. 

Zhao Ming halted in her steps and turned to look at her. She pursed her lips because she understood what Ji Cheng meant. 

Last night after Zhao Ming went to her room, Ji Cheng asked Wen Ru about the bathroom and at that time he found out that the bathroom near the bedroom was for Wen Ru only. 

He didn't put a lock because he doesn't like to lock the bathroom and no one enters his bathroom anyway. There is another bathroom at the end of the hallway which was for the guests. 

Though Ji Cheng couldn't understand his reasoning why he don't like the lock in the bathroom.
