I started watching Kdrama since the start of this year. So far found a few gems that I liked a lot (evidenced by me liking the soundtrack as well):

Goblin
My Mister
While you were sleeping
Reunited worlds

Please recommend to me your best kdrama that is not in the list above! TQ!

Watching currently and my thoughts:

Mr Sunshine - I don't feel the chemistry between the main actors, ie the yearning for each other as the love is forbidden / full of trials and tribulations.

Life on Mars - interesting start but momentum went down a bit in the middle and now picking up again towards the end. because it is set in a world that is most probably in his mind, what happened to him after the first episode didn't carry much weight in my eyes.

Secretary Kim - light and fun drama but i wondered several times while watching whether it is suitable for 15 years and above. Scary how Park Min Young is so thin in this drama that she has to wear all the loose clothing.

Thirty but seventeen - interesting concept so far but the male lead doesn't stand out and the maid irritates me.

Familiar wife has piqued my interest.
