Tin Tin

I don't know if I missed it but did they explain why the couple kidnapped and killed the police officer's wife?? If their motivation for kidnapping Seyun was to get the surgery then why did they do it before?? Just because of a bad drive or was there something else?

Wasn't going to watch it at first due to the rating but I'm glad I gave it chance. Really good overall and I can't wait for Season 2.
