She teaches literature, afterall. If L&P was insistant on working in younger boys then it could be middle schoolers sneaking into the erotica section - older gentlemen works here too. Also, with that as an environment you don't need the hair salon - Claire owns the bookstore? Marie still her daughter? Still works, allows all the relationships to stay basically the same, you don't lose a fetish or a path, and you condense three environments into one.
I honestly don't see a downside to this. What a great idea.
