It is romantic to give a love interest flowers.
Jimmy and Sam have been in the same class all year and Jimmy has developed a crush on her.
Jimmy wants to show Sam how he feels.
Jimmy brings Sam a bouquet of hand picked sunflowers from outside his dorm.
Jimmy brings Sam a new copy of the class textbook and draws a heart on the inside cover.
Sam is charmed by Jimmy's gesture and asks him on a date.
Sam is confused by Jimmy's gift, thanks him, and never bothers opening it.
