Park Minwoo is, by every measure, a success story. Born into poverty in a miserable neighbourhood of Seoul, he has ridden the wave of development in a rapidly modernising society. Now the director of a large architectural firm, his hard work and ambition have brought him triumph and satisfaction. But when his company is investigated for corruption, he’s forced to reconsider his role in the transformation of his country.

At the same time, he receives an unexpected message from an old friend, Cha Soona, a woman that he had once loved, and then betrayed. As memories return unbidden, Minwoo recalls a world he thought had been left behind ― a world he now understands that he has helped to destroy.

无论用什么标准衡量，Park Minwoo都是一位成功人士。尽管他出生在首尔一个令人痛苦的住宅区，且出身贫穷，但他在快速现代化的社会中驾驭了发展的浪潮。现在，他是一家大型建筑公司的董事，辛勤的工作和雄心壮志为他带来了胜利和满足感。然而，当他的公司因腐败问题而受到调查时，他不得不重新思考自己在这个正在经历大变样的国家中的角色。

与此同时，他意外收到了老朋友Cha Soona发来的信息。他曾经爱过这个女人，后来她背叛了他。当回忆自动地涌向他时，Minwoo想起了那个他以为已经被他遗忘的世界——他现在才明白，他是这个世界被毁灭的帮凶。
