This show was amazing! The characters, the action, the soundtrack and the tear-jerking moments. The only thing that I wish they did better was the character development of the older brother. In the end, he only helped his little brother once but he didn't have any redeeming qualities. Even the mother developed into someone you could forgive at the end, sadly not the brother. Another thing that sucked was the ending, it was obviously rushed and I wish they spend more time on it. Another thing that deserved more time was the twins relationship. They still didn't like each other at the end and I wish it at least ended with them dealing with their misunderstandings and forgiving each other. Other than that, this drama was great and I'd reccomend it to someone.
