I originally knew about "Cheese in the Trap" from the manhwa in Webtoon. The manhwa was amazing and I really enjoyed it. Then when I found out about the "Cheese in the Trap" kdrama, I was really excited to start watching it. This is actually the second time I watched the tv show. Although it was great, there were some parts of it that were disappointing.
First off, I loved all of the actors and actresses... except for one. I know she is a great actress and I really like all the roles that she acted in movies but I didn't like how she portrayed the character in "Cheese in the Trap". It was the actress Lee Sung-Kyung. Baek In-Ha from the manhwa and drama were both crazy but Sung-Kyung made In-Ha looked very pathetic and she seemed overboard. I'm not saying Sung-Kyung is bad at acting, I'm just saying that it gave In-Ha a different mood compared to the manhwa and since I really enjoyed her character from the webtoon, I wasn't all so glad. They got some other characters' personalities that were protrayed in the webtoon wrong too.
Besides that though, the plot was amazing and I really enjoyed it. I recommend you watching it, especially if you didn't read the manhwa first (that way you won't be upset like I was).
