This book had an interesting story. There was this girl called "Reina" and she had loved a boy when she was in high school. But after a shocking farewell with the boy, she didn't meet him for the next 10 years, and lived her life at work. One day, when she got invited to a party by her friend, she met a boy called "Haru". He was a cool and beautiful boy, although, he said, "Reina's personality is so ugly". This made Reina feel shocked. Haru said, "I'll change your personality". After he said that he gave Reina a stuffed black cat. If you want to know the rest of the story you have to read this. I liked the book.
