I'm on the "grrrr" side of things too, haha. For those of you waiting on ending spoilers to decide if you should watch the show:
click to show/hide spoilersYun Xian gets knocked up, and she and Qi Yu are back on good terms again. Qi Yu get another personality make-over and finally shows some remorse over stealing Qi Zhen's throne. He promises to keep Qi Zhen's son as the crown prince-- basically, everything's dandy. Aaand then, Mei Lin (Qi Yu's empress) decides to poison Yun Xian. Except Qi Yu drinks it instead by chance. He dies, but not before we spend one or two episodes watching Mei Lin get deposed, Yun Xian become queen, and Qi Yu's mother being all kinds of terrible. Qi Yu *finally* dies in the last episode, and Yun Xian loses her baby because Qi Yu's mom pushes her or something. It was all very draggy and I fast forwarded a lot. She then escapes the palace to just be a regular doctor. "Many years later," Qi Zhen's empress passes away and he leaves the kingdom to his son to follow Yun Xian. The last scene is him entering her home, and the two of them exchange a smile.
I was a Qi Zhen/Yun Xian shipper from the start, but it's a bummer how much they messed up Qi Yu's character. And not even in an interesting-to-watch kind of way.
