The story is simple enough. Nothing too complicated or confusing.

Sad that the pair didn’t get to express love for each other (actual confession). Had hoped for a happy ending. She was such a miracle doctor; they could have changed the story that she could find a way to slow down the poison so either at least they could meet at the end and express their love, or perhaps slow the poison while she finds the cure for herself.
I so want a new ending!!! But all in all, I enjoyed the series.

Always think Joseph is very good with historical dramas, especially wuxia. Wish I could create a Weibo account to follow and connect with him to express admiration.
The FL is pretty but seems a bit older for him - I mean he has a baby face, so (just checked, she is actually 7 years old than him! Makes sense!)
