It was a misunderstanding, Aoi thought it was just rape and with no love, he didn't understand and it came out of nowhere. But it was actually love at the time, and they both loved each other so it's fine.
I know this is an old comment, but what? Even though they both loved each other, no consent was given. Ugh, people need to start understanding that rape is possible even within relationships and marriages. You don't do things like this without knowing you have the OK.
Well If it was me and I truly love my bestfriend and still can't forget him after all this years, I know when he says sorry, I'll easily forgive him.
I don't think I could forgive something like that so easily but that's fiction for ya.
