Great Days with You (Josuke Higashikata x GenderNeutral!Reader)

It's the winter of 1999. You've finally gotten the opportunity to spend the year in Japan as an exchange student from the U.S.. Your host, Josuke, seems super nice, even though you've never met in person before. You expect it to be a fairly normal trip, aside from the fact that there's a serial killer on the loose in the town you're staying in.
