(Uni AU) Killua Zoldyck x Reader: Mystery Friend (on indefinite hiatus)

You are friends with Gon and Kurapika but little do you know that they are also friends with Killua...

Sorry if their ages are not accurate, I tried to make it as accurate as possible but I wanted 'em all to still be in university. I've tried my best to keep the cursing to a minimum and I tried my best to keep the pronouns gender neutral. This is my first fanfic so please bare with the cringe. I would also like to apologize for slow updates. Thanks for reading! :p
