Cecilia, the daughter of a marquis, was taken to the infirmary when her magic went out of control during a practical magic class. She was taken to the infirmary by Crown Prince Klaus, her gentle and beautiful fiancé. She woke up and was taken to the house by a carriage. Cecilia returned to her room safely, but she never rolled up her skirt in her uniform to make sure that she was always worried. Cecilia Lucent (18), who does not remember her at all, assumed that she was anemic the next day and went to the infirmary bed. The suspected Crown Prince Klaus, who came to her in the same way as he did yesterday, when he confirmed that her beloved fiancé was sleeping, he put his hand on his skirt and took off his shorts. He muttered "Cecilia." and put his cheek on his underwear.
