Ah right right now I recall! I did read something about that once!
Yes, the secret is that Yoshiki can't do anything but be sweet with Toshi! XD
You're probably right. Somehow I think, no matter how angry, or prideful he was, Yoshiki probably at least sent him a card. It's the same as fighting with family. You might want to never see them again, but you still send them a card on their birthday or at the holidays because you really don't hate them, you're just upset. =) Now, did Toshi write back? That's another question!
