Bad family! It's hilarious and touching. Loved it. It's about a bunch of strangers who eventually start to care and take care of each other as a real family. Kim Myung Min stars in it and -as usual- is amazing.
3 dads, one mom is about Family, but -again- it's not about your typical family. It's about a few friends and the wife of one of them who turn into a real family, blood-ties be damned. Jae Hee is one of the friends and he's sooo cute! I started watching this drama because of him and then halfway through it, I was smitten with Jo Hyun Jae *headdesks forever* Eugene is nice, too (and this isn't coming from a fan of hers).
I've also heard good things about The sons of Sol Pharmacy, but I haven't watched it yet (will do, VERY soon).
Unstoppable High Kick (with Jung Il Woo, woohoo), but it was a daily sitcom and i didn't feel like commiting to such a thing (it has waaayyyy too many eps, omg).
