Moongazer

Kaguya, the protagonist of "Moongazer," is a striking beauty, but behind her back she is referred to as a "doll" due to her lack of emotional stability. She has a twin brother, Kosumi, who is a successful ballet dancer, and has decided to go overseas to meet him after graduating from high school. When her parents remarried, Gyoji became Kaguya's stepbrother, but he doesn't believe that she wants to go abroad and is worried about her. This is the story of a girl who has suppressed her feelings in despair about her future, and the 10 men who surround her.
