Venom Readalong: Week 2

This month, I will be participating in the readalong for Venom by Fiona Paul, the first book in the Secrets of the Eternal Rose series. This week, I'm taking on questions pertaining to Chapters 9-16, and I will aim to be as spoiler-free as possible during these posts so as to not ruin the book for people who haven't read this story yet!

Venom is the story of Cassandra Caravello, a girl growing up in the elite class in Renaissance Venice. But despite her seemingly charmed life, she's felt trapped and alone ever since her parents died years ago. When Cass stumbles upon a murdered woman, she's drawn into the dark underside of the city of water, complete with courtesans, killers, and secret societies. She's also falling for Falco, a mysterious and mischievous street artist with a knack for finding trouble. But there's the murder to solve, and her far off fiance to consider...

This week's questions:
-In this chapter (9), Cass comes across prostitutes up close for the first time and finds herself enthralled by the strangeness of it. How would you, as a high-class girl, have reacted?
Well I definitely would have closed the door if I had walked in on what Cass saw, that's for sure. I probably would have been much like she, and the best analogy I can think of is like a tourist. She was seeing a side of life that probably intrigued her, but made her incredibly uncomfortable because of who she is and where she comes from.
-Why does Cass wait so dang long to read Luca's letter, even though she takes notice of it almost every time she passes?
Ever since delving into Venice's underworld and the dangerous games of secrets, I think somewhere in Cass's mind she believes that ignorance is bliss. After all, if only she hadn't wandered to the cemetery that one night, she would have never found herself in this mess. Sure part of her finds it exciting, but she's also terribly tense. Plus, even though Luca is an arranged fiance, she's basically cheating on him with Falco and she's feeling guilty about it.
-When Cass asks Falco "Why should I trust you?" he responds, "Because you want to." Is that a good reason for trust? Why or why not.
To me, that is absolutely not enough. Wanting to trust someone and that person actually being trustworthy are two entirely different things. I get that Falco is Cass's love interest in all of this (duh), but I don't really trust him at all, frankly.
