The feeling was similar for both the dramas.
The main similarity I felt was , both r Cinderella themed one..

Both r revengeful and romantic kdramas. City hunter is a modern era drama whereas TPM a seguk. Both has strong female leads. Also both leads r attached to the villains on hunt.
Give it a try.. It won't disappoint u...

Felt it similar.
Both r having strong fields of thriller romance and some revenge.
I even thought that both the lead male had very much similarity in some where. Try it ..

Its also a mermaid story. Bt much bettr than " the mermaid". The only thing is its a Korean drama

Another gumiho story with the star lead as lee sung gi.. Really good...

Very similar to heartstrings.. Revolves around a set of students where the central theme is achieving their dreams and music.. And most similarity is the music itself.. Both have wonderful music.. Very calm and warm.. Worth a try..

In both the movies the plot is similar. Here instead the female lead is struck with the tragedy of cancer. The main similarity is at the end both the leads determines to contain that only one love and being in that love.. Try it

Its because the both shows depicts a determined girl who loves a very popular guy and try to Achieve his heart and love. Here also we could see a love triangle .... Try it.
Note this drama is based on business rather than highschool and college

This is also a lee jong suk drama.The story is much more compelling and competitive.. U will race with the time. Like in W here also the growing romance between the two leads r very much cooler. Also the ending is much more adorable which I felt a little lack in W... Pinocchio really amazing media drama....

Here the plot is a love story developing from a business deal which is much finely pictured here.. Also the love which develop is so amazing to watch...Go for it
