He's name is zaynx, and he's a secret mafia boss and you're his wife, one day he didn't come and it's so late so you direct his location and it shows in the club and you get angry because he doesn't inform you so you go to the club and he's sitting with a girl and you gets more angry you just go and slapped her but zaynx stops you

(So it's only for the new mafia mission that he has to become that girl boyfriend but only his team and zaynx knows about it and no one, not even that girl)
