My Dear Mr. Gu

After dating a terrible man for six years, she was the last to learn he was getting married. Then, in a shocking turn of events, she became his sister-in-law. This older brother was said to be a cold, ruthless King of Hell. He was hailed as the most handsome man alive, but the more handsome his face, the colder his heart. He was also so fastidious that he wouldn’t let women near him. Uh... Well, not only did he spoil her and indulge her at every turn, he also joined her in getting revenge on the scumbags. Was he the one who started those rumors himself? Was it all so he could wait for her?!!!
