I normally dislike harems because they're usually all the same and boring, however, this is incredibly funny (last two pages for example) and I actually like the MC because he's not a huge pussy and loving his girlfriends. He loves them and like most other protags isn't too much of a bitch to show it.
This manga never fails to make me laugh, god I love this. Still I wonder how the authors will manage the number of casts and keep up the same energy in the future.
