On a battlefield where countless lives are lost, Fine, bullied by her own family, worked as a military doctor in that harsh environment.

One day, Leon, a ducal knight, was wounded on the battlefield and brought in. The one who responded was a Saintess dispatched from the church. She was Fine's biological sister, showered with her family's affection.

However, the Saintess sister screamed at Leon's horrific state and fled. Fine, taking her place, then magnificently healed Leon without so much as changing her expression.

A few days later, Fine receives a marriage proposal from Leon. Fine assumes, "Lord Leon only wants my healing magic; there's no love involved," but in truth, Leon was deeply, madly in love with her.

"I'd heard rumors that there was a Saintess on the battlefield, but now I'm certain. You truly are the real Saintess."

Gradually, Fine's extraordinary healing magic begins to become known throughout the world... *This is a heartwarming story with a happy ending.
