She sells her socks...Except she kind of didn't charge him for it? Actually she gave him extra service as well...
Great ending though. So, that charm he said looks weird was actually a gift from him, huh. Which is kind of ironic because I guess it actually worked as a good luck charm?
Because of it he recognised her in the selling socks ad(Though I think it was pretty obvious even without the strap), and it brought them together.
... I'll just leave this right here.
