At first everything was confusing but when you watch and analyze everything it's so satisfying to the feels. Geumja may seem insane for what she's imagining and planning or even saying but I bet you she's one of the coolest and wisest characters I've seen. And her love for Jenny is the best thing ever, personally my most favourite scene was the translating part from Geumja to Mr. Baek. ATONEMENT, DO YOU KNOW WHAT THAT MEANS?

Although how they punished Mr. Baek wasn't so satisfying and brutal unlike in Sympathy for Mr. Vengeance, I guess he's better of dead.
