Yu Qianqian
So I just rewatched the show for the second time after letting it rest for only a month, which is so unusual for my. I usually let a show rest for a year or so before revisiting. Anyway, Yu Qianqian says she comes from very far away and we see in her back story that she does rescue breathing and chest compressions to save Qi Min's life. She says only by dying can she go back home. I think the first time watching my thought was, are they trying to hint she may be an immortal/demon/god. But this second time through my thought was, is she a time traveler? Like, a whole story opened up about her with these small interactions we only get hints of.
Is this in the novel or was this just a tool of the writers of the series? Anyway, some thoughts that have gone through my mind.
Oh and did I miss how Qi Min's face miraculously healed to perfection after 17 years? It was supposedly messed up when he met Yu Qianqian but 6 years later, it looks flawless.
And sorry, I would do the magical blocking thing for spoilers but my Samsung flip phone has a giant white line running through the middle of it (two actually, making a cross) and seeing things is tough on this phone.
