During the Republic of China, such theme drama I had already watched . It is kinda boring but bearable . Acting is good . About story what had I understood that two lovers who worked under different agents one side consist of good people ,they were soldiers and other side bad people they somewhat were doing smuggling. The male lead was adopted by them but he had no idea for what cause he was working with them and in this way the story had begun . Don't want to be a spoiler , so give it a try .
