I love antagonist couple of drama "Marry my husband"

I have read the webtoon "Marry My Husband". Contrary to the comments of readers who have read the webtoon and then watched the drama adaptation, I personally prefer the main couple in the webtoon and the antagonist couple in the drama. In my personal opinion, the main couple's acting felt unnatural, while the antagonist couple is funny, acts well, and I really liked the two actors who played them. The screenwriter did a great job in writing the story. It is more logical and suspenseful than the webtoon. In episodes 11 and 12, BoA appeared as the male lead's ex-fiancée. She looked older than him, sorry, almost like an aunt and nephew. I think she was made to look older by the makeup artists because she was playing a villain. I'm a fan of BoA's music and it made me sad to see how she looked in this drama.
