This drama is just...WOW!! Way better ending than Rooftop Prince and the acting is even more fanstastic! Better OSTs and everything. Plus KIM SOO HYUN *(drools)*

The shows have similar plots about secret births and rich and middle class families becoming in-laws.

Both main lead males are in film industry. Couples have to fight through family disapproval, status, and office politics to be able to maintain love and life.

both dramas are on food. you will enjoy watching these two dramas cook Italian and Korean cuisine. you will definitely crave it.

Birth secrets, big families, heartwarming relationships, arranged/contract marriages and appealing heroines. Even though ISGY has more evil people doing evil things and the characterizations are a big rougher, if you liked OB and its storylines, you should give ISGY a go.

Both are about a crown prince who loses his crown princess at the begining

Same writer and director. Plus the stories have simmiliar cute and light feeling with main guys chasing after female leads.

Basiclly the same plot :) And with good-looking guys too :)

The same plot :) Looking forward to it :)
