Reporting a bug.
You can get 2 flowers before healing the daughter of the woodcutter. (One in the beach, and one from the cliff which black-haired girl helps Jaja get it.) And you will use one when you interact with the girl in bed. And after exiting from the dream (and before talking to her mother) you can still interact with the girl again and it would cost you one more flower, which makes it impossible to proceed later.
