You are not far away, but our mc will never sub. Kat is more dominant than Darlene, but the main idea of different jobs is for the evolution of our mc.
The difference path will have more effect over the MC's personality. If you choose Darlene's job, you'll be kind, romantic, try to take care of your "household".
On Kat's job you'll turn up to be doing shady stuff and would be more like a bad guy, who doesn't believe in love, no strings attached and would ask for things in return, when doing something for the household.
