Later they do fall in love and get together from what I heard but if I remember correctly it does not happen within the next few arcs... can't give him too much happiness nor distract him from his cultivation just yet, it is one of the issues with Xianxia's the same thing happened with Coiling Dragon, either you delay the romance of a man/woman's life or you create some sort of barrier to achierve said romance.
Edit: Btw I do not think the love that they both feel for each that was present in the latest chapter has yet to evolve to the point of the kinda love you desire. Right now it is closer to familial love in my opinion as both from everything I have seen do not have family connections due to being apart of the cultivation world. And both were likely kidnapped by the reliance sect
