Tbh I'm really annoyed that it's his "fault" that both girls were fighting over him when what they were doing was not his fault and their own actions. This idea that a guy attracting woman to fight over him is somehow his fault needs to die.
It's not, and even if it is, the fact that he's apologizing is what's actually pissing off Mozu. As you can see in page 4, she sulks after he apologizes yet again.
I kinda get it, especially after the dad's explanation near the end. Mozu prefers Suzuki when they're constantly competing for who will triumph over who, which is why she has been
constantly provoking him in the last 2 chapters. But instead of fighting back, All Suzuki has been doing the last 2 chapters is apologizing.
Imagine you are a very passionate Smash player, and you have another friend who beat you once so bad that you stormed off angry. Now, whenever you provoke him to another game, he keeps refusing to play and apologizing for making you angry the last time, when in reality, what you want as a very passionate Smash player is to keep playing until you beat him again.
