Since reincarnating into a fantasy world, Kaoru Aoyama has been succeeding in her new life as Patience Granger. She's changed things for the better in the Granger household despite having to live away from her adorable younger brothers in the Royal Academy's dorms. Her first school term is over, she passed her exams, and it's time for summer break! Patience has all the time in the world to play with her brothers, work on the garden, and make money for the family... Just kidding. She's given an offer she can't refuse from the queen herself: spend her vacation at the royal family's summer palace! She's devastated that she'll be apart from her brothers, but wait, there's more! Summer break with the royals means keeping busy fulfilling Princess Margaret's demands, managing Prince Keith's moods, and being pulled into a special project with Prince Richard. Fortunately, Patience is ready to use her skills in household magic-along with knowledge from her previous life-to survive the summer!
