Nothing is new about the plot. I would gasp at the screen or cry my heart out but I wouldn't be surprised. And strangely that didn't push me away -I who lives for surprises-. The story might sound typical; or it is typical, but the journey of those people trying to heal the open wounds is something everyone of us can relate to. You can hate none of the characters even if you can't bring yourself to justify their actions. Each of the characters presents a part in us; whether we admit it or not. The characters are so human we can simply sympathise with how weak they and we are. Watching them changing each other unintentionally, watching sincerity going through and watching the wounds getting healed even if they leave a scar was like watching my life in a flashback. The only difference is that my wounds are still unhealed. The drama evolves around family relationships and society's views on them. It tackles the struggle single mothers go through in order not to abandon their kids. For society they're damned anyway. Whether the mother has the child or abandons it; she'll be cursed. The whole world gives its back to those poor women. The drama as well questions the family. What makes a group of people a family? Is being born of the same parents the only way to become family? If you find yourself suddenly a family of someone, how would you react? How much would you sacrifice for your family? How much would you forget and how much would you forget?
