Bleh, bleh, bleh Thank you all so much! I've been getting so many amazing comments even though it's been years since I wrote this. I would like to let everyone know that this is a finished work, but I still really enjoy seeing that people like my writing- even if I might be a little embarrassed by it now.

Y/N L/N is introduced to Killua Zoldyck by his Mother, Kikyo Zoldyck. Kikyo planned on getting these two to get married. Killua is against it at first, but when he knows it was her, he agrees because he meets her in the past. The two starts to develop feelings for each other. Then they starts to date each other. But unbeknown to them, Killua's elder Brother, Illumi Zoldyck is obsessed with Y/N. What will happen next? Read and find out the story. Disclaimer : I don't own the anime. Storyline belongs to me. Edited: Read the A/N in the Prologue before commenting. IT'S IMPORTANT
