"I'm sorry for LETTING you get hurt"
What the hell kind of bullshit, responsibility-avoidance is this? She straight up attacked him. There was no "letting" him get hurt. She hurt him. Maybe it was justified. Maybe it was unjustified. That's not my issue. My issue is that she refuses to take responsibility.
And this is just me speculating, so I'm at least being clear, but this just looks like herp derp, cute girl, so can't make her be unappealing, have to lessen the blame on her, herp derp. That's what it looks like the author is doing.
