So the time travel AU has me by the throat, I just-
I just imagine how Xiao Lanhua thinks about staying away from Dongfang Qingcang, but
remembering how he's been trapped in the Haotian Tower for 30.000 years and imagining him staying there for many more centuries is just cruel; he does not deserve such a fate (plus she won't let Lord Changheng die when trying to strengthen the seal). Ergo she ends up doing the same thing as before and frees Dongfang Qingcang yet again
she also ends up going to Haishi city, despite knowing that this will lead him back to her, but she can't just sacrifice another person (then there is also the Destiny Book of Chidi woman, which she needs to take care of). Of course, she tries not to get caught or hurt, but again things don't go as planned and the second meeting ends up happening anyway (he also tells her the same thing about her belonging to him which just-)
So this whole " staying away" backfired spectacularily because he ends up staying in Arbiter Hall with her anyways, and now she has to deal with her own emotions.... I mean, she hasn't seen her beloved in over 500 years and now he's finally there in the flesh but she can't really do anything about it. He does not have the memories of their time together, and worst of all, there is nothing to remember because for him it never happened. It all happened in another life for her.
She tries to keep him at arm's length but it gets increasingly harder.
Then there is this whole mess of him being able to feel her emotions...
(I can also imagine that she still acts as if she doesn't know who he truly is and maybe she explains her confusing feelings away with having feelings for him? Which is true? Lol, I don't know, at this point I'm just brainstorming)
