So, tell me, does the MC ever become more than an insufferable little bitch?
The girls all seem likable enough, but this MC deserves to have his hand held, walked to the nearest subway station, and pushed in front of an oncoming train.
You should have spent some time making people care about the MC before making him simply disagree with everything that anybody says to him. His "trauma" is an abstract concept, and it bears no relation to the character that we are meeting. It doesn't generate empathy towards him, it just makes reading the dialogue tedious.
Maybe it's your plan to make the MC an egregiously annoying character, and that would be a bold choice. However, I've invested barely an hour reading this story, and I can't even conceptualize a reason to spend another minute doing more.
So, without spoiling the story, is this what the game is about, or is there a compelling reason to continue enduring his whining? (And, no, naked cartoon girls are NOT a compelling enough reason)
