Elsie, a girl who was abandoned by her parents at an early age and raised in a convent, is an apprentice sister who is loved by God. One day, when he was living a fun monastic life, his father suddenly appeared and made a forceful request. "If you don't want your donations to the monastery to be cut off, please take your sister's place and live in the royal palace as His Majesty's wife candidate." Elsie became a candidate for princess in order to protect her favorite monastery. I'm confused by the new life I'm not used to, and His Majesty the King is a scary person...but as long as I pray to God, I'll be fine! The tomboy sister's life at the royal palace begins at her own pace!
