3-bu Seijo no Shiawase Gutara Seikatsu - "Kimi wo Aisuru Koto Wanai" to Iu Kimajime Jiki Koushaku-sama to Enjiiru 3-bu Dake no Raburabu Fuufu. Ato wa Jiyuu! Yahhoi!!

The saintess Noisha is about to die of exhaustion when she is given in marriage to Lunan, the young heir to a dukedom. Lunan offers her a contractual marriage with only one condition: they must play the loving couple in front of their friends for three minutes every morning.

This is a drastic contrast from her previous life in the church, when she was overworked to the point of exhaustion, to a life of only three minutes of effort every day. The newlyweds began their first "lazy life" at their own pace! However, instead of laziness, Noisha is demonstrating the power of a saint for the sake of others.

Lunan's bewilderment and the servants' doting love for her never stops...!
