The first side chapter was okay (I'm starving for good exploration of kink in mangas) , he took out the vibrator because it was too much but then he completely for goes consent in the next chapter? That's not how it works. You can't revoke the right of consent, ever. You can pretend for rape play but that's why we have systems in place in the bdsm community. So disappointed because the story was so wholesome up until now
At first I thought he was gonna be a golden hearted asshole and probably end up with the mc but I was wrong, he's just a jerk what the hell. He gets off by violating ohns boundaries but that's forgivable what's not is the way he treats the guy he approached for looking like his ex, and now he fell for ohn and probably won't even even tell his brother or feel remorseful. I don't particularly like ohn or seowoo but I hope the author follows up on the hints that ohn likes og seowoo more than fake seowoo (he gets butterflies when he thinks about seowoo and dislikes when it's jaewoo acting as his brother) and doesn't have jaewoo as endgame
