It's been a year since Ruby first received an anonymous letter in the school locker. Today she received it again. The first letter Ruby received was when she was in 1st grade of high school. At that time she was confused and afraid. Suddenly, in her locker there is a yellow envelope. She brought it home. It turned out that the contents of the birthday greetings were written in beautiful sentences like poetry. The handwriting is neat. Along with the letter, there was a painting of a rose in the moonlight and had the words 'In a moonlight garden, when roses never fade' written on the back. What does it mean? Ruby never found out who sent the letter. All she knows is that she has a secret admirer. Maybe. But if it's true, how cool is that. But to be honest, Ruby was really curious. However, she never told anyone about it. Today Ruby received it again. The envelope is still the same, yellow. Realizing that someone had bothered to deliver it to the locker made Ruby flutter....
