I would un-watch this series if it could. I read the bad reviews and still went ahead.
What is wrong with the lead actress's acting? The lead actor is still okay NOT good, just okay. The chemistry is just not there even in the most cliched romantic scenes they have. The only thing that interested me a little was the lead actress's mother's backstory and the cause related to it. I have been watching dramas for the last 6 years and my advice is to spare yourself by not watching this.
