This is set in Qing dynasty, one of the more judgemental and oppressive periods in Chinese history as far as women were concerned. She was held hostage by rebels and stayed with their general for some time. No one would believe she is still chaste. To make matters worse, she and anyone who shields her is now a traitor to Qing. Even if Gu Pingyuan is ok with her reputational issues, the rebels have been ousted from their hometown by the Qing troops. Which makes anyone linked with her a traitor to Qing for saving a rebel leader. She had no choice but to defect to the rebels and flee to Hebei and she ran into Ms Su who helped her. She made a decision that sets Gu Pingyuan free and allows both he and her ailing father to live out the rest of his life in the village instead of on the run from Qing forces. Of course it helps that that she fell for the general. But regardless, this is her best and only option. To be honest, this part feels a bit of a stretch to me and I have reason to believe this is not really the case in the novel.
Actually Bai Yimei did what she had to do. Of course it doesn't hurt that she empathises with the general, feels responsible for his life and is attracted to him.
It's been so long since I found a drama I like so much that I end up binge watching it. Really glad they added this to Netflix so more people can watch this masterpiece. Also LYX and HMH are both so gorgeous and their chemistry is 🔥. And I loved how they handled the poison plot with maximum emotional impact
Have fun in your next journey!
