This so sounded familiar. I get the wanting things to be organised logically and trying to come up with strategies to cope with the world, Oh boy do I.
I can see the logic of deciding that if you're not good at something, like dating, to experiment with it and test how it should work, and how numbers are so interesting.
Stella wants to settle down and marry, it's the next step for her life, not least according to her mother. She decides to hire someone to help. Into her life comes Michael who uses his good looks and charm to make sure his mother is getting the medical help she needs. Michael has rules about not getting involved with clients but he finds Stella compelling. He understands her and wants her to have a fulfilling life, but he's not sure he's enough for her. Meanwhile Stella is getting used to wanting to have someone else in her life, she cares for Michael and it's somewhat confusing her.
I liked it, liked the characters and the fact that they all had their own agency, I did want to punch her co-worker.
