Right before the final episode, I was angry at this drama towards the end.
The little sister is my favorite character. I'm happy about how things turned out for the sisters.
The extra scene after the false credits feels like some of the best closure I've received from a drama.
It was very satisfying to see growth and maturity in the characters over time.
Not all of my questions were answered, but the most important ones were addressed. I'll take it.

It's worth a watch from beginning to end. It was painful to wait for the episodes to be released and the cliffhangers made me feel frustrated. I even waited a day or two to continue the next available episode. Either way, great drama.
