Read the synopsis and then started the drama at episode 22 onwards.
Why no start at the beginning?
I was watching another ongoing drama when episode 1-21 was broadcasted.
Thus there were many spoilers in facebook/youtube.
Got a rough idea what was the storyline during this duration.

King of Cdrama OST Zhou Shen sang the ending theme, thus it brings all kind of feels. This was the main reason why i watched this drama.
After finishing the final episode, the ending was a cliffhanging ending.
Was there HEA or not? leaving me in a limbo. This is why I am 50/50 to recommend this drama.
There's no novel that i know of, to follow up on the actual ending.
