Well, the Jill sleep-rubbing thing is on her (unless the MC chooses to take advantage of it), but the MC definitely does a lot of stupid, irresponsible shit through Episode 5 even you you cling to the CHICK side.
As you say, I find the Bella path borderline creepy (especially if you skip staying with her in Episode 4). And while I like the CHICK path overall, it's still more about the MC fooling around than it is about serious romance. I'm hoping that will change someday, but it's sure been resistant to go there.
Even with the effort to repair the mansion in Episode 6, it's clear the DIKs may become more productive and proactive, but they're still a bunch of frat bros. So if someone can't stand frat antics, this is probably not the game for them.
(Personally I dislike such antics, but I find the rest of this game makes them tolerable in comparison.)
