(from ebookjapan):

The Rose King says he will grant any wish if you create the best rose worthy of being called Venus, the goddess of beauty. The Murray and Bodard families, both rose artisans, are at odds with each other in their attempt to cultivate a rose that will be favored by the king.

The daughter of the Murray family, Mylène, and the son of the Bodard family, Alain, fall in love as soon as they meet at a party.

Undeterred by the opposition of others, Milène and Alain nurture their love and try to create the Venus rose.

In addition to "A Tale of Roses", "A Midsummer Night's Dream" and "Marie in Light Blue" are also included in this collection.
