"I will never love you for the rest of my life."Saint Noisha is ransomed by the young next Duke Lunan on the verge of dying from overwork.There was only one condition for her contract marriage presented to Runan.Playing a lovey-dovey couple in front of her friends for three minutes every morning. A change from a life that was overworked in the church to the point of running out of extraordinary strength, and a mere 3 minutes of work a day.The start of a newlywed life where you can master the first "gutara life" at your own pace! However, far from Gutara, Noisha, who demonstrates the power of a saint for the sake of others,Runan's confusion and her servants' doting can't be stopped...! ?
