What the hell? You girls— he is the ONLY one who didn't get to 'vent'!
This is why I hate these kind of harems, they feel written by an alien, (I am including Mato seihei no slave), you put the protagonist in a situation that seems like a "dream" but at best it only benefits the women. Is like the author is choosing to not understand his own sexuality, how frustrating it would be.
I refuse to believe he is fine with this, that his GF is fine with doing these things instead of taking time together, at this point she is bringing NOTHING to the relationship but just using him, is like one of those fantasy stories where the protagonist is super useful in healing/enchanting/whatever and in the meanwhile the rest of the team is doing their own thing.
She is supposed to be the GF, but how could you tell based on her behaviour here, they haven't even kissed yet, I can't remember the last time they have gone on a date on their own, she is just lending him to other people, parading him knowing she OWNS him and he won't do jack shit with other girls, she can read his mind and still chooses to do things that benefit her most.
What is she bringing to the relationship?
I feel like I am progressively getting more pissed at this story as time goes on. Is just disappointing, the birthday is probably going to be some more "fanservice" that is nothing more than what we see here. What a waste.
