I'd imagine part of it is the fear that no matter how hard or sincerely given the apology is, there's no guaranteeing it will be accepted.It's very simple thing ...
Yet
The hardest thing to do
And often people wait until way too late to do that
at least he was brave enough to admit his guilt for not being by Mikoto side after that awful incident in middle school. she also gave sincere apology even though she pretended to stop being friends and gossiped about mikoto behind her back after big incident she went through
the apology was easy but now think about the local couple supporter's reaction because you just know she is right around the corner listening in.That was easy, TOO easy...
What's the catch?
