Yu Dong saw that her husbands were done so she turned to Lang and said " Lang, go and take Fang Chi to his house. It's late, I will worry if he goes back alone" she would have taken Fang Chi herself but she didn't want unnecessary drama to start again. It was alright from her though, after all, she wasn't as shy as Fang Chi, her little fiancé was as jumpy as a little rabbit, it will be troublesome if rumours were to start again.
Fang Chi was just too - timid. She didn't want to take a risk and in case it backfired and Fang Chi did something like the last time he did on the cliff, so instead of taking him with her, he decided to send Lang with him. Compared to her, Lang was a much better option, the latter was her subordinate and her strength and fighting skills were improving as well so she was at ease sending Fang Chi with Lang.
