You are right friend, I am full on your side. The h-scene with Miru at home was totally blueballing. Or the good night fun in MCs old room at his parents home, or the sex scene in the gym. All of this was totally blueballing.
I will tell you a secret, if you turn Miru always down, or say no, you don't have to wonder that theres no content.
There is also the possiblity that you one of that kind that get only off when cucked - fine by me, I'm not here to judge. But then you can't say this game is blueballing, just say "I want to get cucked and theres no content for me here" - yet...
Or you don't like Miru (heretic!
), then you can say there is no content for the LI I have a interrest for. But straight up complain there is maximum blueballing is borderline retardet bullshit.
You know what blueballing is? The first episode from Dating my Daughter, MrDots is still the unrivaled king of blueballing.
