The first drama I have watch with Lee Joon Gi in it was Time Between Dog and Wolf. I felt in love with him since then. So I watched lot of other Joon Gi's dramas only for him. I watched Iljimae even if I hated historical dramas and then Hero, two weeks. I was very happy to see him for like 30 seconds in she was pretty :P. I watched Scholar who walks at Night but I didn't enjoy it very much so I was less motived for Arang and the magistrate and Gunman in Joseon, because as I said I'm not fan of historical romance. I recently watched Moon lovers because of Lee Joon Gi, Ha Neul, Ji Soo, IU and Baekhyun. I was very happy to see a drama with all this great actors in it.
I rarely watch a drama without knowing any actor in it. I don't like to read synopsis because some of them spoil the story events so the cast is my only reference for choosing a drama to watch, plus popularity of course.
So I watched :
for Lee min ho in boys over flowers : I am Sam, Personal taste, Heirs, City hunter and Faith
for park shin hye in you're beautiful : Heartstrings, Flower boy next door, Heirs and Pinocchio
for woo bin in Heirs : School 2013, Uncontrollably fond, the film twenty but I couldn't watch more than 20 min
for hyun bin in secret garden : hyde, jekyll, me.
for Lee jung suk in I hear your voice : Secret garden, School 2013, Pinocchio and W
There are lot more like kim soo hyun, ja na ra, ji sub, Hwang Jung Eum, infinite members, Ji soo, Song Hye Kyo, Ji sung etc.
