I'll start by saying that Tokyo Juliet isn't even half as good as My best ex-boyfriend, not like the last is any good..but they're both about fashion and arrogant childish guys who won't let go.

About brothers, their love lives and their paths to maturity. Both series are comedies.

Qin Zi Qi is very similar to Gook Seung Hyeon, both are heirs that have to go incognito into their own firm and the main female teaches them how life should be lived at work.

Meeting again after they choose to separate. Faith makes them reconsider their feelings.

The same premise. In both series the wife tries to make amends so her mother-in-law can accept her.

The main character loses his memory and falls in love with the main girl but he has to return to his real life and love interest. Who will he choose?

I found the two series relatively similar, the men are strong fighters, you cry your eyes out watching random scenes (either because you cringe for the bad acting or fangirl over touching that man's perfect body), as always the main girl is annoying, stubborn as a mule and won't take no for an answer. The perfect nosy woman that people like for no apparent reason.

The difference between the two of them is the fact that Suzy can't act and Jang Geun Suk is cutter than Lee Seung Gi.

Conclusion?! Just watch Hong Gil Dong it's actually much much better..

Did you ever had that "ah, they're so twisted that they're perfect for each other" feeling while watching a couple?..if not, you'll have it watching both series.

In Rooftop Prince the evil woman is so good at playing her role that she convinces you to hate her with all your guts and pity her craziness, all at the same time. She gets you at the point where you love to hate her. Same goes with Gyo Chae Yeon, with the difference that she isn't as humane as Se Na.

In both series one of its characters wants a child without getting married and tries to convince the man to sleep with her.

In both series the main lead is an eccentric immature man, both are romantic-comedies that involve a violent woman, both have the main female act all innocent when it comes to relationships.

It made me think of the situation Ki Tae's mother had to go through and probably many other ahjummas around South Korea. While Sa Geum Ran is at the age where she can still change her life..there are many pitiful women around the world who lost their courage and live in pointless marriages because they're too afraid or have no other opportunities to start anew. With age come the problems..and it becomes harder to let go.

A man changes himself to get revenge on the woman who broke his heart.
