Proteja o Chefe (2011)

Both are romances about a non conventional rich guy trying to win the heart of strong willed/stubborn girl. Both male leads are reluctant about being pushed into positions of power. Both female leads are aggressive, and self-righteous. There's scheming based on jealousy, and classism, that stand in the way of both couple's happiness. There's also great chemistry in both!

Both are love stories between a secretary and the CEO/director. Funny and sweet.

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.

an unconventional male lead who is also a wealthy son but has many on going personal/mental social issues. Ends up falling for the girl that is hired to work for him. Characters are better written and portrayed here than in RL. IMO hehe :)

Actors Park Young Kyu and Park Sang Won have similar characters in both dramas, such a funny and childish character, a father who does not grow up whatever progress in an age, keep of being a mama boy, although he has sons! ;'D

Office romance with some comedy. Both are about how a girl allows a guy to become successful in work.

Both are office love.. director and secretary love.. both dramas have two directors who love same secretary..

Has the same theme of a feisty poor girl capturing the heart of a rich guy who fights with the girl constantly.

This really felt similar to Protect the Boss except with a spy theme. The main girl is the same in both.

Both star leading actress Choi Kang Hee. Both deal with a social phobia that stems from a repressed memory and trauma. Both have adorable funny leading men and even more handsome 2nd leads. Both have tender moments and upbeat endings.

Both dramas feature an immature, arrogant and wealthy business man falling head over heels for a poor and feisty girl. Both male leads are quite obsessed with the female lead, and comedy ensues.

Another strong female character, lots of fun scenes, some angsty bits, and pretty ppl to look at!

Excentric rich male CEO falls for female staff assistant who aids and supports them, bringing balance, clarity, and meaning to his life. A jealous scheming counterpart and a female whom everyone thinks is a better match for him.

Both are an office romance between a boss and an assistant. Both are funny and the assistant manages to change the boss for the better.

in both dramas the employee helps the boss to become a better person.
