First of all I love lone-wolfs. But this MC reasoning is weak. When you find out his backstory you realize - looking back at the beginning — he’s just a traumatized child!!
He’s actually distant away from people, the whole time with a blank-expression on his face — All due to the one reason only... He talked smacked to a little girl once when he was a kid, she had influencial parents that threaten all the classmate kids Parents, school board, and got his mother fired from her job, cornering her in becoming a neet novel writer. Now isn’t that just f*cking excessive?? The mother tried to fight it in city hall but failed, made things worst. So he stays distant as if it was a prison-cell or foregone conclusion. Basically gives up. Yes, he was that traumatized and in shock! They could had just moved cities... and wtf is a girl that influencial doing in Public School? Probably going to give her a sad backstory too. So he stays distant from the Harem — Because it’s hopeless since he believes himself targeted now and fears betrayal and they too could become a target. Which is absolutely stupid. Just move to another city or country if you feel that restricted...

Second all she’s a ghost, what’s with her promising loyalty? It’s not like she can be influenced or targeted in any way.

Third of all, this is modern society, surely that sh*t illegal.

There’s more I want to say but I’ll leave it a time that

that has existed since the dawn of time
