City Hunter (2011)

Both male lead were taken away and raised by a man, to be hitman, to do the dirty work, to be gangster. They infiltrate to be a spy, but step into good side and turn against the man that raised them.

Similar atmosphere and general plot devices. A male lead that is nearly alone in this world who gets sucked into a mysterious, dark plot connected to their past. Tons of action, investigation, plotting, revelations, kidnappings, etc. While City Hunter's characters and plot are a bit more sophisticated than Two Weeks, both are still enjoyable.

A young kid were trained and raised by a mob.
As they grown up they were told to do some dirty work, mission to kill
However, they change and they want out, they realized right from wrong

Both dramas consist of:

Action
Hidden Identity
Leads are tools in Revenge
Little bit of romance sprinkled in the mix

Both have young men who are really good at being a soldier. Both have young men who carry their teams and strive for better.

because of the mystery revolving around the male leads, the prosecutors, there`s not much action in PP as in CH but still...and the love stories resemble each other even though in CH he wasn`t taking revenge on her but even so, and i feel like even the OST is similar ^___^

Quite a leap from melo to action thriller - but City Hunter is also a revenge thriller and it's great to see how very different a basic premise like that can be handled. It also handles themes such as is love weakness? Do you need to hide yourself emotionally to be successful or to survie? Plus another lead pair with superb chemistry; really welll acted evil mastermind, a truly comic retainer in the City Hunter's ahjussi; and a cute bromance!

Even though IHYV isn't over I get the same feeling as I did watching City Hunter both kids train they're butt of to avenge their father also they both fall in love and want to protect the girl at all cost. Both are amazing shows and are a must see and will leave at the edge of your seat

Lee Min Ho stars in both dramas as the main character, but of course, not the same character.

It's about forbidden love. It's filled with romance and comedy but filled with almost the same action as City Hunter. You will love it!
