Given the following context:

Sergio is a Toronto pastry shop assistant who is smitten with Hattie, a mousy girl who works in her father Perry's diner and refuses to consider a relationship with him until he begins to earn a decent living. An opportunity presents itself when Linzer, Sergio's employer, offers him $20,000 to torch the store so he can collect the insurance money and use it to give his wife the lifestyle he feels she deserves. Sergio declines the offer, but one night the bakery is burnt to the ground anyway.
Sergio is offered $25,000 to take the blame by the millionaire father of the real culprit, the mentally unstable Garet, who set the bakery on fire as a public declaration of his love for his society girlfriend Stephanie, whose attraction to Sergio, unbeknownst to her vengeance-seeking beau, is unrequited. Despite his innocence, Sergio claims responsibility for the fire so he can use the money to claim Hattie as his own. Linzer, however, has second thoughts about allowing Sergio to pay for the crime, so he confesses he did it, while his wife insists she set the blaze to prevent her husband from being imprisoned. Sgt. Zikowski is left to determine who of the four claiming guilt is the real perpetrator.

answer the following question:

Who's attracted to the pastry shop assistant? 

Stephanie
