Synopsis

"I will never love you for my entire life." The saintess Noisha was overworked almost to death when she meets Lunan, the young heir to the duke. He offers her a contract marriage with only one condition: they must spend three minutes every morning pretending to be a loving couple in front of his friends and family. This is a complete change from her life in the church, where she had to work to the point of exhaustion, to now only having to work for three minutes a day. The newlyweds begin a "lazy life" at their own pace! However, instead just being lazy, Noisha uses her powers as a saintess to help others, which made the servants treat her with doting kindness, much to Lunan's bewilderment...!
