Ace the first five races with PRC. A fax will come through from one of your biggest fans, none other than Reiko Nagase herself. The best part? She's supposed to remain neutral but is so happy with your performance she sent the fax anyway.
On Racing Team Solvalou, Enki Gilbert goes from treating you from "some random nobody who I don't owe respect to even if he wins" to what is effectively a surrogate child, because you remind him of his late son. By the time you get to the last race, he's outright concerned for your safety, urging you to please just finish the race safely because he doesn't want you to die too.
