"Smarty had just started his journey in Galar a while ago, but he was not able to bring Diancie along sadly. He didn't mind too much about it, as his friend would watch him go from beating the first gym leader, to defeating the champion of Galar himself. One day, when he was going to the Crown Tundra, Diancie sent a message she has time to come visit him and possibly throughout his entire adventure. When she came, Smarty was happy to see her. They both hugged and she said how much he missed. When he was asked to rest on the floor, Smarty did so as she took off her white flat shoes, sat on his crotch, and give her lovely trainer a face massage with her lovely soles.~ He missed how much her feet smelled and even made his face smell like her feet.~"
