Synopsis
Late 19th century, London, England.
Helen, born and raised in a wealthy family, loved sketching plants and animals since childhood.
Her knowledge of mushrooms, in particular, was profound, and her sketches were remarkably precise.
However, her unique perspective, which could find beauty and stories in ordinary landscapes, was often seen as eccentric, leading to numerous matchmaking rejections...
Her mother sincerely wished for someone who would truly understand Helen to be by her side.
Ron, who had just joined the publishing house inherited by his older brothers from his father, was struggling, having been assigned to the non-core children's book department.
He was the sickly third son, completely unregarded by society.
One day, Ron discovers Helen's postcards brought to the publishing house.
Strongly drawn to the breathtakingly beautiful drawings and warm stories, Ron persuades Helen, and her first picture book is published.
To simply live happily with someone who loves you for who you are.
An original musical that pays homage to the life of Beatrix Potter (1866-1943, England), the author of "Peter Rabbit."
