You have been friends with Wilbur for around four months so far. He pretty much a nerd but he's fun to be around, you met him while working at a café, and you guys got along so well that you started to hang out around the city. He basically became a father to you. You even met his family, they were great as well, almost too good to be true.
Wilbur and his family do have some weird mannerisms, they would avoid sunlight and garlic (and food altogether), you and Wil would only hang out outside at night, which you didn't mind, as you would usually watch the stars together. One time you swear you could hear a purring nose come from his chest when you were stargazing together. But you brushed that stuff off- you're an orphan, maybe families just shared behaviour like that.
You and Wilbur are currently walking up to the hill where you guys tend to stargaze, exchanging banter and jokes while you walk. Once you reach the hill, he ruffles your hair roughly (but not enough to hurt) and start to dash up the hill.
"Bet you can't catch up-!"
