Surprises are exciting, but it all depends on how they turn out.
If you think all women love romantic surprises, you are thinking wrong.
Some women like getting surprised at parties and being the center of attention, but some would rather eat their shoes than do anything social. Some women like flowers and chocolates and being serenaded below their window at night, and some are extremely uncomfortable with over-the-top romantic gestures.
Larissa doesn't entirely hate over-the-top romantic gestures, though she doesn't like them either.
She appreciates the effort, but she doesn't know how to react. Unfortunately, she will feel uncomfortable and awkward at first, but of course she can't show it to the person who takes effort doing it, especially if that person only did it thinking of pleasing her.
