It means it was much deeper than anyone could’ve anticipated. And he didn’t notice the cut, he only realized it was there because the MC winced while eating. It when he looked in his mouth that he saw the cut which was oddly deep for him to have simply bitten into his own cheek on accident.
It’s annoying because he caught the MC (I was personally looking forward to seeing how he would react to one of the MC’s transgressions) but the ML managed to survive this entire time because he’s so cautious and suspicious of everything.
He definitely is annoying but he's the man who killed that boy's family. So he has all the reasons to be extremely wary of his boy toy
okay but fr nobody is going to notice a cut to the side of the mouth EVER like this man is so annoying why are you making it such a big deal
