I feel like the fl falls in love with the ml due to stockholm syndrome....
It's not stockholm syndrome. She's not kidnapped nor is she confined in a position where she has limited choices. She sees more than the eyes can see, she somehow see that beneath all the lies and the facade, the ML is actually a decent guy. I mean, he's saved her time and again and that's where you'll notice that things started to change for her.
I'm mostly convinced, the shifu who sends her back, is the ML.They're making a point to showing her younger self,…
This is what I think as well, that the ML is actually Er Yu and by some weird cosmic thing he also gained powers to send the girl back in time to eight year before all the war started.
