A hairless quasi-immortal century-ish at the time old super smurf wearing an "I'm not the step dad, I'm the dad who stepped up" shirt living with his much younger wife and her ex-boyfriend's son. Almost forgot about the equally as old platonic life partner drone paracausically connected to the smurf by the unknowable will of an eldritch space marble.
There's nothing really wrong with any of that, but it's like saying Clark Kent and Lois Lane have a normal relationship.
