You should induce both. However which one you induce first depends on your target.
You should induce passion first if your target:
-seems bored all the time.
-has a routine they're stuck to, e.g. a job.
-appear to have no substance
-cerebral/stuck in their minds.
The definition of passion is "strong and barely controllable emotion." NOT ONLY RELATING TO SEX.
I'll use myself as an example. If someone wanted to make me obsessed--they'd have to induce passion within me first. There's no need for me to leave my home as I make money from home, as well as making money from home--I don't speak to many people. Aside from writing (which I love), I have my own little investment fund, and make sure my other finance business operations are running smoothly. While finance and writing for you guys, is a passion of mine, I yearn for a Different in what way?different passion.
You should induce security first IF your target:
-they've had a traumatic childhood
-are easily triggered
-traumatic experiences with relationships e.g cheating
-have dangerous jobs
Your victim here would be the opposite of my example. Perhaps their careers are unstable.
