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