I haven't watched the original movie but that's not necessary to watch this. I wouldn't say I had high expectations but this show didn't disappoint. Everything was delivered well, from the characters storylines, to the acting and their morals and the OST is addictively good and perfect for the series. It being based on a true story really drives the message more home and it's so much more than simply cheating on exams. The couple's are cute, funny and the friendships between them are equally as special. One fault I did find was sometimes the background music made scenes feel too dramatic as it was unnecessary but the suspense really gets bigger and bigger as the schemes escalate.
