Ju Rui Ying Xiang

She, the unpopular fourth girl from a remote town, came to the capital to get married, hoping only to return home in fine clothes. He was born into a noble family, with both civil and military skills, but he was far away from his hometown and became a hostage, singing and dancing every day, living in drunkenness and dreaming. He was forced to become a puppet monarch. He was trembling every day. He seemed to be aloof, but his life was precarious. He has a family full of loyal people, but his family was brutally exterminated. He only relies on an iron gun to find justice and regain his freedom.
