Looks like it’s a regular vanilla happy end, well sans the swinging. Which is in line with this author.
My only disappointment is something I saw coming a couple volumes ago. Susa never really has anything going for him outside his friends. In and of itself that’s not a problem, but he’s shown to have low confidence because of that. Having him suddenly slay harems of cosplay chicks (which he didn’t even manage to do on his own, they were, again, given to him because of who he knew) and the self assurance to go through with this pretty complicated arrangement with no growth ANYWHERE ELSE in his life seems hollow. Hard to root for him, he just comes off as an isekai protagonist at this point, getting pussy is not a personality trait lol.
Also, camera girl was best girl.
