Duet

Age range 3 to 7

Sora and Sarah are twins. They do everything together: go for walks, share favorite sweets and the sweetest tunes. But when Sora begins to grow up, Sarah does not. Sarah is an imaginary twin and she doesnt grow up. What will Sora do when her new school friend, Kay, comes to play? Will she stop playing with Sarah, or is there another solution?
