Right now?

Yu Dong paused as she slowly turned to look at Shen Li, she knew that even if she could hide from others, she will not be able to hide anything from Shen Li, in fact, she did not want to hide anything from him either. So, she took a breath and then turned to look at Shen Li, their gazes met and she could see that Shen Li though looking calm was nervous, if she wanted she could have lied but if she was to do that then she would only give Shen Li a shock in the future. 

And was there a need for her to lie?

" I do," Yu Dong honestly replied. "  But you don't have to worry, I will not bring me in the house until you all accept him." What she did not say was that she will not bring Xiao Hua into their house if Shen Li were to refuse, she was willing to wait for the four of them to accept Xiao Hua but she would not leave him. This was her bottom line.
