Amoura was in her apartment because she thought she was fine. She felt her life had no meaning since Sergio Aguero decided to leave her life without caring about her. Who knows what he really wants to do with her. But one thing is for sure, she is so hurt and lonely. In fact, he is usually fine when Sergio leaves.
He was probably angry and disappointed that she had played with his feelings. But she had her own reasons for not accepting his declaration of love. She still needed time to heal the wounds she had suffered in the past. She is also fighting for her rights as a woman who has been betrayed not only by her husband but also by her own sister.
Amoura does not deny that she sometimes still thinks about Dominic Toretto, her ex-husband and current co-worker, even though he is in a lower position than she is in the company, which is now wholly owned by Sergio Aguero after he made a fatal mistake and forced Dominic Toretto to sell all his family's shares.
