Synopsis:
Rose, a librarian who came to Scotland to heal the pain of a broken heart. Then he meets a former famous F1 racer, Mt, but he takes a terrible and rude attitude for the first time. He believed that Rose was a meha fan who had been sneaking naked into his bed before.
… That's the twin sister, Rebecca. I thought, but when Rose did not tell the truth, he asked Rose to pretend to be a fiancee, saying that it was the perfect job for a woman like you!
