Marissa hasn't felt embarrassed in all her life, than she was right now. She didn't know what actually went into her to make the first move to kiss him, she's such a dreamer!
A big one at that, what was she expecting?
That he would kiss her back? All Giovanni did was walk away without looking back, as if her touch repelled him, making her think that something was wrong with her, but it's not entirely pointless, there was something definitely wrong with her.
She craved for attention, for his affection that despite how fucked up her relationship with him is, not withstanding the fact that there hasn't been any stand as to what they meant to each other.
But Giovanni knew what he wanted, a contracted wife and she's nothing but a daydreamer, who was expecting that he would fall in love with her and marry her for the sake of their kids.
What is wrong with you, Marissa?
