It was waaaaaay different from the webtoon. It was very cringy and I would say Moon Gayoung did a waaaaay better job in the great seducer. I felt like this drama was a whole different story from the webtoon just had the same title and the same character names.
I mean, if you haven't read the webtoon then go ahead watch the drama. It's like any other high school/campus teen romance drama. But if you read the webtoon and are trying to see if you want to try this drama, just don't watch it. You'll be disappointed.
