Succubus cunt. If he was truly being controlling he would be isolating her from even talking to your cunt ass.
All the dude has done is lay his boundaries and your whore advice is having her cross them.
Should he be more understanding to the fact she's a succubus and her biology causes her to act and be a certain way? Yes. Is he too prudish for a high school boy? Yes. But that doesn't mean he can't have high standards just because his girlfriend is a succubus. It just means he's dumb in picking out a girl he would want to date.
He laid down how he wants this relationship to go in the beginning and giving her advice to cross his boundaries is cunt behavior.
If I was in this scenario where she said her bullshit of "Women don't like controlling men" I would respond with. "Keep your third party bullshit viewpoint out of my relationship with her. I don't need to take advice from a literal whore pushing her bias on me." Because he's not controlling her in the slightest. If the heroine wanted to leave because she felt she was being restricted too much she could but she doesn't because she does like the MC. If she did decide to leave after the MC laid down his boundaries I don't believe the MC would force her to stay. He'd probably blame himself despite being right.
Yes agreed, I hope the manga doesn't stay as the primary reason the MC and heroine aren't progressing in their relationship, as in romance mangas leading in throughout the story with a manipulative and disliked (by readers) third party (someone influencing relationship.) tends to skew the climaxes in the romance area of the story.
I guess MC being a pure vanillafag shouldn't be remotely surprising, lol.
Also, you idiot, if your gf had had more demon friends she would've sucked you dry by now and you'd never know what hit you.
