How to Kill, Kil (KilluaxReader)

The Gala

I made a plan
Step 1- Get close to him
Step 2- Get him alone
Step 3- Kill him?

Maybe that's to obvious, of course I'll kill him... You hesitated still not very prepared for this night.

You put on a light baby blue dress that didn't pass your knees. You put some sparkling heels on and put a little makeup on. Your put your hair up in a elegant but messy bun. The perfect outfit of innocents, no one will suspect that you are going to kill anyone.

                                      —————           
At the gala everyone kept coming up to you saying hi and things like, look how tall you've gotten, you've grown so much and look how pretty you've gotten.

It was weird for so much murderers to come together and act like friends.

You looked around for Killua and finally spotted him. He was leaning against a wall alone. You walked over to him casually not trying to make it to obvious your trying to get to him.

"Would you like a drink." A waiter asked you, you're around 10 feet from Killua.
"Uh sure." He handed you a drink, then you looked at Killua. "Killua! Hi!" You smiled and waved you started to walk towards him. He looked a bit confused but waved back.

"Hey Y/N, you look..." You raised your eyebrows waiting. "... Interesting." Your eyes went wide.

Interesting?! 
He deserves what's coming for him... Maybe not but what the hell.
He's only wearing a black suit what makes him normal?
"What's that supposed to mean?! You look... You look short." You said with sass.

"Short?! I'm taller than you." He stood up from the wall and measured us with his hand. " You've got heals on anyways. I'm not short!!!" He was true you're usually about 4 inches shorter than him, but with heals you were 3 inches.

"Well I'm a girl so I'm supposed to be shorter than boys, but usually it's more shorter than this, so your short." You shrugged.
He ran his fingers through his white hair and rolled his eyes. "I am not short shut up."

"So how have you been? I haven't seen you in a while." You asked Killua awkwardly.

"I've been pretty bored lately, but good I guess. What about you?" Killua replied awkwardly as well.

"Oh I've been just great... Doing stuff you know."

"Doing stuff with who. Your mom?" He said sarcastically and calmly.

"Huh what? I don't hangout with my mom, I have friends!" You said angrily.

"What friends?" He asked he said in his casual voice.

"What friends do you have? I have a lot of friends believe it or not." You said as you crossed your arms.

"I have a lot of friends... You just don't know any they live far... far away." He was embarrassed.

"Thats what I thought." You said proudly, you noticed that Killua always talks in the same voice and usually never shows emotion, it's always the same level of deepness and tone level. The perfect voice for a true assassin, you were jealous.

You two talked for a while, Killua was easy to talk to, but he was honestly mean. He made rude jokes about you and insulted you a lot but you could tell he didn't truly mean it.

                                           —
"This is so boring." You said.

"Yeah why does everyone think it's so special to be an assassin." Killua said.

"Hey guys my family kills random people for a living, aren't we cool!" You said in a mocking voice.

"Do you want to go somewhere else.?" Killua asked.

Shit. I forgot, how could I forget. I have to kill him. But I actually like him. Shit.
I don't want to. But Dad said if I don't... I have to.

"Like where?" You asked.
"Well there's a bunch of rooms in this building... How about we get some food then find somewhere to go."
"You know what would be funny..." you smiled mischievously Killua looked at you eyes widened.

You two hid under a table where all the food was.
"So are you going to tell me what we're doing or not?" Killua asked suspiciously.

"We are going to steal the food." You said innocently.

"How much?" Killua asked.

"All." You smirked.

One plate by another you two took food and hid it under the table.
"Now for the final thing..." You grabbed two cupcakes and came out from the table.
"You won't." Killua said seriously.
"Watch me." You threw two cupcakes as hard and as far as you could and hit a couple then ducked under the table.
"How stupid do these people have to be to not realize the foods missing?" Killua smirked. "Let's not throw the cupcakes, pie, cake, strawberries and chocolate fountain." He clearly had an addiction with sugar because he kept eating them.
"How would we through a chocolate fountain." You asked.
"I don't know... You're weird like that you'd find a way."
"I'm not weird you're weird, I am just socially challenged." You said well grabbing more food and throwing it.

"What the hell is socially challenged?" He said well also throwing a handful of mashed potatoes.

"It's when you lack social qualities." You said throwing a pile of little weird crab things.

"Social qualities? I think that's just an excuse for being weird and awkward." He said throwing fish.

"Well whatever it is, you are socially challenged." You said.

"I am not! I-I just am not as annoying to people as you." Killua said in a embarrassed tone.

"I'm not annoy- Shit, I think someone saw us. Let's take the cake and run." You both grabbed the cake and cupcake and ran. You turned around some old guy was walking towards us furious and you threw a cupcake at his face.
You both sprinted into the elevator and pressed the top button.
Killua is fun, how am I supposed to kill him.
Get over it. I need to do it. As soon as possible.

You walked out of the elevator onto the roof.
The roof had a long garden filled with flowers, there was a railing made of glass around the edge and there was tables spread out around.
