Some viewers are upset about the 18+ content in K-dramas, especially since the rating was initially listed as 15+ on MDL. Now that the rating has been corrected, it's unfair to blame the show for the unexpected mature scenes. Instead, you should direct your frustration at MDL for this problem.
Can someone explain why it's considered as a flop? For a Mon-Tues drama it peaked at 4.4% ratings which is like 90% of TVN dramas have similar ratings in this timeslot. Also don't forget it's a 18+ show. When it was airing it was #1 at Tving and VIU. Seo Ye ji even topped the most buzzy actor's list for a week.
Also when it released on NETFLIX after 2 years it still managed to get on Top 10 Non-English TV shows.
The writting in this drama is getting worse with each episode. Just too much of fillers and boring episodes.
