It's entertaining but bad.
The idea of sisterhood, found family and friendship is really good, that is my favorite part, but everything else is just meh.
The beginning was boring and it dragged for too long, it took a couple of episodes for the story to actually start going somewhere, i think it could've been perfectly fit in a 16 episodes drama, instead of 30+
Some moments are fun and i actually really loved most of the characters, besides the main couple, because they were too bland. The "villains" were the worst part. They don't have strong motivations, they're just mean because they can.
The side stories were the best and I would actually rewatch certain episodes just for that.
It's not terrible, but it's definitely not good either.
