I love you, Mira," said Darius, kissing her as usual. Our contractual marriage was supposed to be a loveless relationship that lasted only two years?! Mira, who grew up in an orphanage, was born with the ability to absorb magical powers and was constantly forced by her adoptive father, Baron Weston, to purify swords and magical tools that were filled with a miasma. As a result, her body was so battered that the doctor told her she would not live more than a year. One day, Mira collapses in the temple and is saved by a beautiful woman, Anneliese. Her brother, Darius, is the first duke and head of the Order of the Holy Knights, but he is suffering from a disease called hypermagia. Anneliese offers to help her brother in exchange for saving Mira from the baron. The heroine has the power to suck magic power, and the hero suffers from hypermagic. The only way for the two to survive, with only a few days left to live, is to *kiss*??!!
