Yes! Most of the clients are dateable except for any clients not attracted to women (in the demo, this only applies to Rachel).
However, I ended up designing the MC's personality to be professional and somewhat reserved. She will let her guard down when encountering her clients outside of her office. At first, these are shown as chance encounters (running into Zaid at the smoothie shop, Cliff at the restaurant, taking Dean to the vending machine) but over time she will choose to spend more and more time with them and her feelings will develop.
I'm really glad you enjoyed it and appreciate you taking the time to comment. It really helps make my day.
