Prosecutor Princess (2010)

Ma Hye Ri is a woman with an excellent memory and ability to focus, which allowed her to pass the bar exam with ease. Despite her talents, she is more interested in being fashionable and dislikes hard work so she is far from being an ideal prosecutor and has doubts about her suitability for her job. Through her conflicts with senior colleages and struggles with difficult cases, however, Hye Ri gradually matures into a brilliant prosecutor with a sense of duty and justice.

both are revenge melodramas where the guy despite his attempt to manipulate the female lead to exact his revenge rather ends up falling in love with her

The main premises are very similar even when the tone of the two dramas are different: the main heroine is a prosecutor who has to discover the wrongdoings of her family. In that task, she is helped by the main male lead who has been wronged by her family.

Same writer and main lead, while the plots are completely different, they both have similar atmosphere..one sided crush, female lead getting bullied at work, gentle male lead..etc.

In both dramas, it feels like the female lead is really underappreciated for everything she does. They also both carry similar themes (lawyers, personal issues) and have romances which, although light at a first glance, have a deeper root. If you liked Prosecutor Princess, then Divorce Lawyer In Love might be even better, as the secondary characters also have better and deeper development than in PP.

Even though the plots are differents, in both dramas there is a person who purposely befriend somebody (in both cases the daughter of a President's company).
In Prosecutor Princess, the theme "revenge" is more marked.

In both dramas the lead male approach the lead female in order to seek revenge from their fathers: revenge leads to love.

For the love part it seems similar. It is very similar in how although the girl fell in love with the other guy first, but there is another guy who have been supporting her all along. The guy who have been supporting her all along have a secret, and he also have a female best friend that seems like a rival to the main girl, but is actually the one supporting their relationship.

Only resemblance is strong, brighter personality of the female character and a bit of mystery to the story. Liked it.

Both the histories are about female prosecutor and their daily, but the histories are interest with unsual events.

Both dramas revolve around the law where the leads work as a lawyer or a prosecutor.
The female leads in both dramas are not the typical people to find in the job as they are very fashion forward (aaaaand both of them love the color pink). They both have a great memory but are somewhat airheads which makes their work hard in the beginning. The male leads in both dramas help the female leads out and they, of course, fall in love with each other.

Both series show the story about man who wants to take revenge on father of the female lead. Prosecutor Princess is more romantic comedy with a twist of revenge. Beyond the Clouds is a crime melodrama.
