If he is laid-back, does he really “quest” to get rich? That seems somewhat contradictory. I like Richiev’s title ideas. Very clever. But, when did the man-child become a con artist?

I think, once you resolve who the man child is–his predominate character traits, then this might begin to gel a bit more.

Finally, is the twelve year old girl the antagonist? Or could a court order child protective services agent be involved? What if having the twelve year old in his life, ultimately can fulfill his desire to get rich because she has a trust fund but he must first change his ways and learn a lesson–his arc.

Lots of potential here.
