In real life time it'll be several months from now at the earliest, unfortunately. But in game it won't take too long once that part is actually created. I was originally planning for it to come later in the game, but I did some galleries of Will hooking up for Patreon, and after seeing how those turned out I realized I didn't want to wait too long to make him a hookup option in the actual game haha
I'm glad you're loving it!
