However, Alyssas bravery soon wears off and she starts to second guess her decision as she struggles with loneliness and being away from her friends and family while fitting into a new culture. But as she continues to work for a wealthy family, she becomes mentally stronger, and when she sees Manhattan for the first time, and shes determined to succeed in her new city.
One cold evening, Alyssa is on the rooftop of a townhouse and she locks herself out. There she encounters Gilles, a wealthy French man. Their relationship grows and they become deep and loving friends. They soon marry, even though Gilles is in another loving relationship. Through this friendship, Alyssa is lifted out of the grinding poverty and loneliness of her life as an immigrant, and into the world of wealth, glamor, and fashion.

One weekend in the Hamptons, Alyssa confronts Gilles about hiding his relationship with Mark, and what it means to be free and in love. As Gilles thinks about his life, Alyssa is contacted by Rachel, an art dealer from Arizona. Rachel and Alyssa strike up a friendship, which leads to a surprising story twist.
