Is it worth reading? I heard that he has other women other than the MC.

MAJOR SPOILERS

Yes in the most recent chapters released on mangago he has 3 concubines. He does not love them (or even like them, he barely knows them). The female lead (main character) has expressed absolutely no romantic interest towards the male lead and seems to enjoy the company of the concubines. The male lead likes the female lead.
Imo it's a relief that they're not together, it would feel very artificial ^^'

If you want spoilers, I have posted one before.

It seems the manhwa is also going on the same direction as the novel. And I highly recommend to continue reading it until the end :)))

You can start from chapter 140 in the novel ^^
Man...till the end I feel bad for her sister and parents. They never got to know what happened to their child. How painful that must have been.
it would have been enough if they atleast got to know that their child is alright. And living a happy life.
