That call from her Dad seemed so heavy and her reaction so obedient it made me feel like was something so complicated... but if Xiaoen saying now she'll be her life raft solves everything im fine with it. No need to think too much about logic here. Just want her to be free and happy with her peach farmer girl.
But Yundou position, tho understandable, its very awkward. Like, how will she feels when things work out for the 2 when she was clearly so against it? Also, even if is to protect Xiaoen, she was too cruel to Xingyuan. Mostly after clearly noticing she was in a bad state.
