Ai no Campanella

Oliver, a boy who grew up in an orphanage, falls in love with Eva, the woman who is supposed to be his guardian. But Eva has a secret... A boy and his guardian. A dorm mother and a student. A woman and her fiancee's brother. Set in 1960s England, the story is about the love between a boy and a woman, both fulfilled and unfulfilled. Is it pure love, or are the feelings illicit? A brilliant debut full of fascinating details!
