Is it possible to get a not-interested SIM to be romantic without a cheat??

Out of boredom, I had an occult sim start unleashing different spells to see the effect.

One NPC is not interested romantically with men or women, and is not open to trying it.   When the occult sim does the infatuate spell, she’ll go over and kiss the character that I want.  When she does this, I notice a bump on the romance relationship.   However, when trying to flirt with the NPC, it’s still greyed out because not interested.

I haven’t had enough time to play around with it, but I was wondering if anyone had tried to be flirtatious with a not-interested sim and wondered if doing the infatuation spell enough times will work.
