Description: "I'm an apprentice nun! My dream is of course to become a good nun!" One day, three apprentice priests appear in front of the main character, who look good but have the worst personality. She thought she would be able to get along with people who have the same aspirations, but at first sometimes clashed with them. However, with the help of the main character's innate cheerfulness and the help of his childhood friends and seniors who always care about them, they gradually get closer. Something that sprouted in the main character before long. It was "love" that yearned for only one person. However, what the church needs is "equality" and not "special" love for one person. On December 24th, the church will hold the Holy Night Festival. The main character is forced to choose whether to aim for "nun" as it is or live in "love".
