In Dill town, you can only buy herbs at Pepper's Store, and you can only buy blooms at Rosemary's Store. In a strange coincidence, any time Basil is at Pepper's Store, Lily is at Cherry's Store, and any time he is at Rosemary's Store, she is at Rosemary's Store. Basil is buying flower of the dong quai plant. Where is Lily?
