Yes, ML is originally a transmigrated character. The only odd one would be NH, in the original story she was not a transmigrated person. I totally agree she is on the road to love BUT her past life and her knowledge of the original story hold her back from knowing the feelings of love or even recognize what they are......she just feels a little bothered or something. ML just hang in there and don't betray her.
From the way LQX is behaving towards Nan Hua, I honestly don't think there is space for "FL" anymore. If LQX and NH had not transmigrated maybe things will have been different. But these are different souls (or whatever they are). I hope he stays true to her, NH doesn't know it yet but she seems to be falling for him.
