Emily, the only daughter of an earl, is looking for a marriage partner to inherit the title. Kyle, the captain of the Order of the Holy Knights, appears before her at just the right time. "I need you," he says, "and you need a suitable husband." The two agree to pretend to be married for the duration of the contract. But Emily falls for Kyle during their fake marriage, and soon the three years are over and their contract comes to an end. However, Kyle returns from an expedition with an unexpected case of amnesia. "So does that mean he doesn't remember the marriage contract?" Emily thought, realizing that if Kyle knew, he would be horrified. (Source: Kakao Entertainment Corp., translated)
