I've been watching Asian dramas, i.e, Korean, Taiwanese and Japanese for over a decade, though I've been in Asian drama hiatus in between till Boys Over Flowers. I've watched more Korean dramas than those 2 mentioned above. We've been seeing Kpop idols that ventured out into acting.
I'm not really into pop (mentioned this dozen times). Rarely that I notice the actor's acting, maybe because some of the dramas that I watched was dubbed in Filipino. Aside from having a different plot/story than its Filipino counterpart like Mara Clara -- the finding-of-the-diary-epic drama, boy! Korean actors/actresses are pretty! Before when you say Kdrama in Philippines its right away melodramatic and will make you cry (hello Endless love and Stairway to Heaven!). Oh I said I'm not into pop, well you can find kpop idols in most dramas now! In fact one reason that I started digging into Korean music was because of their OSTs, love the Korean ballads (Sung Si Kyung anyone?) and of course those cute cute cute actors!
