You strap on the headset and see an adversarial generated girlfriend designed by world-class ML to maximize engagement.
She starts off as a generically beautiful young women; over the course of weeks she gradually molds both her appearance and your preferences such that competing products just won't do.
In her final form, she is just a grotesque undulating array of psychedelic colors perfectly optimized to introduce self-limiting microseizures in the pleasure center of the your brain. Were someone else to put on the headset, they would see only a nauseating mess. But to your eyes there is only Her.
It strikes you that true love does exist after all.
