Just Between Lovers or Pinocchio!

just between lovers

Just between lovers -> pinochio -> six flying dragon

Pinocchio.  Just Between Lovers is a good one to follow it.  

Nirvana in Fire

Those not recommending it have never seen it- it is AMAZING!!! High score for a reason

Nirvana in Fire. 

Then Just Between Lovers and Six Flying Dragons.

Pinocchio then just between lovers

Just Between Lovers

just between lover was amazing

Am I the only one that loved Deep Rooted Tree?

...Although I also  recommend to watch Just between Lovers first.

Six Flying Dragons is for sure the best drama on your list based on my taste so I recommend u to watch that first
