Story: Some may say it's just a typical storyline about twins, but I really liked the way it was played on this one. It's very interesting and most epis didnt give me a boring vibe. It's really fun to watch. Perfect for a weekend drama, where you can relax while watching. It's heartwarming and has some funny and exciting perks.
Characters: I really commend Da Hae's acting here. She's very good! I can really feel the sense of polar opposite twins here. But since it's a drama, there are some absurd encounters not surprising. hahaha, but still, it's really fun. Cho rong is really a favorite here haha. I guess, annoying characters is a must with this kind ofstory. I feel frustrated sometimes and angry (w/c btw shows that the characters are good)
Music: Didnt notice something hip, so I've just given it a passing score
Rewatch: Since this is on my Most Recommended dramas, this will have a very high rewatch value.

I love the drama. Tho I never expected I'd love this kind of genre, still, I have fun and enjoyed watching it every weekend. thumbs upp
