Well, that made ABSOLUTELY no sense. It looked like MC was humiliating the girl more than the guy. Why did the guy even get irritated? Not one minute before, he was about to kill her, why would he feel jealousy of a person he didn't love or cared for? Yeah, the author MADE him feel jealousy and attack MC afterwards, but I'm just saying that it makes no sense for him to react this way. It's not like he coveted the girl in the first place, given he'd just confessed to her how he always hated her guts, and five minutes prior, he even thought the girl was already dead anyway. This was pretty stupid, and in now way does it bring closure to the girl getting revenge.
