Think of it as a token of support. No one in Valhalla holds ill will towards Ai. We've spent the majority of the last several years as best friends, it just turns out that this is an example of best friends who shouldn't get married. As Grendel said, this is just a bumpy part in Ai's history, and it's just a bumpy part in the relationships that created Ai. We've no intention of throwing away friendships because of a misunderstanding.
