If you're into somewhat dark stuff, I'd suggest "Ashita Mama ga Inai", a 10 episode drama focused on orphans, as well as "Hirugao", which focuses on adultery (it recently got adapted into a Kdrama).
You can check out my mydramalist as well if you would like (I watch a lot of dramas from Korea, Japan, Taiwan, China, a few Thai, and a few from the Philippines):
i only ever saw one but i remember being pretty entertained: seigi no mikata (ally of justice).
its about these two sisters; the older one is really terrible and the younger one always ends up doing everything for her, but things always work out so that people outside the family never find out that she's so terrible. its supposed to be i guess more funny than dramatic; if it weren't for how incredibly convoluted a lot of the situations get it would feel a lot more messed up (also, as an older sister who bosses her younger brother around, i dont really have the high ground lol). its been years since i saw it so my memory is a bit fuzzy on particulars.
