I'll borrow the words from another comment section of some other manga by the same author with the same themes (wall hole sex): "the author builds a kind of icky story around it that is supposed to end in heartwarming love, and it just doesn't really work for me"
It makes no sense. [spoilers]
the older bro is twisted enough to let random dudes bang him at a shop but gets teary eyed and jealous like a pure virgin girl when he thinks his lil bro may've fallen for his co-worker? tf

    it actually makes sense. it means that sex is not that big of a deal for him, but he has feelings when it comes to love. he separates sex from love. i like it, it's really cool.
