Big Man (2014)

Both of series have the same main actor Kang Ji Hwan, who will return to take vengeance toward the people who wronged him.

Literally the exact same show. They're both bad and both are sure to leave a bitter taste in your mouth :).

Monster has Jo Bo-Ah and the setup is decent, which are the only good things to say.

Both dramas are about taking revenge, the story lines are a bit different but the main ideas are the same. Greed destroys you.

Both protagonists want nothing more than to achieve success in their professional life. They also can't help getting involved in their surrounding matters, even if that means putting themselves in dangerous situations. Both men lead face multiple struggles in order to climb on top, and they have a naïve view on how tricky people and corporation life can really be.

Well, aside from the fact that the lead role is played by Kang Ji Hwan in both the dramas, both of these dramas give off a similar feeling and has a lot of suspense to keep you hooked up and wanting to know what happens next. Worth watching.

A rich man with a big brain Vs a poor one who got nothing from his life, and the same war in the business sector. both of Park Yong Ha and Kang Ji Hwan got the same character, while Kim Kang Woo and Choi Daniel did a perfect job in a bad guy role! heartless, no mercy, and scary mind!

I recommend this both drama because , Male lead and Female lead
