Killua has developed his first ever feelings for someone how does he react to it? This is my first ever story on Wattpad or matter of a fact first story I have ever written so please leave comments on your opinions and I will work my hardest to try and do it. By the way this is just one version of this story once I'm done here I will put one up of Kurapika and then Gon please enjoy and share your thoughts
