I don't think what happened is going to matter here. [As if that is some kind of reassurance.] But if you go back, it would.

[Unless time can also be altered, there isn't any going back for him.]

I want to keep being your friend, Ryo. [It's offered earnestly, but Akira has never really not been earnest when it counted.] ...So I forgive you.
