Gon is depressed. What happens when his secret gets revealed.(they're already dating) (they are both 18 now) (maybe smut)

Killua has a desire for gon~?

Gon is a normal teenage boy. But all that has changed since he met a dog named killua that could turn into human called inuhama. HunterxHunter AU

The phantom troupe, the most dangouse group in the world was holding a young boy, Gon Freecss. He became troupe member 4 when he was 7 years old and has been training amongst them even before that. When Gon is 12, he takes the hunters exam and meets some friends along the way like Kurapika and Leoreo. And he also meets Killua. They are 'best friends' during the exam but do the two of them think of it as more than that? Or is it really much more?
