I don't think this makes his life more interesting as much as it makes it more exhausting.
But for the record, I don't see Chantal as Peetz' sole problem in life. I'm sure he had bouts of depression before he moved in with the Chin. It's just that having someone like Chantal around you for pretty much the entirety of every single fucking day will most definitely drain you. Bibi had his work and video games/anime to escape to, Peetz just strikes me as the type of guy too weak to say "No" when she's calling for him from the kitchen whenever she's in need of attention, distraction, or a servant. But this really is a hell of his own design.
