Ten years of exhaustive study and sleepless nights have suddenly been rendered meaningless for aspiring Imperial Physician Lin Qingyu. In the midst of his education, he’s instructed to set everything aside and marry Lu Wancheng, the sickly son of the marquis—all in the hopes that this union will heal the illness that plagues the young master. However, Lin Qingyu quickly discovers that Lu Wancheng isn’t just an ill-fated aristocrat. In fact, the man has a mysterious sixth sense that could help Lin Qingyu outmanoeuvre anyone, even royalty. Thus, Lu Wancheng proposes an idea to his new male bride, one that will help send Lin Qingyu back home to continue his studies and fulfil his dreams...both benign and dastardly. Yet as feelings bloom between these new allies, a dark truth threatens to rip them apart in both sickness and in health.
