Im looking for dramas, that have

- female lead as a main protagonist

- love story

- family stories (with more than just one family in it)

- heartbreaking and shoking moments

- antagonist you just feel like u want to kill

... Just something like Golden Rainbow. Or Secret(Ji Sung)...I miss watching a drama, that nearly made me going made and crying...

Come! Jang Bo Ri come in my mind, i don't know if is makjang (I'm still unclear about what this means) but you have here a female lead as protagonist (Bo Ri), a character you want to kill (Yeon Min Jung), a love story, or better say 2/3 love stories. An also some complicate family stories...
Korean tv series
- Endless love
- Stairway to heaven
new tales of gisaeng (not as melo as GR and Secret but a great female lead and romance)
may queen 
can you hear my heart (it's more focused on the male lead )
