Kari's POV

"Goodbye everyone!" I bid farewell to my bestest friends, Gon, Leorio and Kurapika as me and Killua went the same direction.

"Bye Kari-chan! Bye Killua! I'll see you all tomorrow!" Gon cheered while Kurapika just waved and Leorio nod.

Killua stared at me for a while before waving at me and disappearing from my sight. I then sigh to myself and shoved my hand into my pocket. I look up the sky while a tear fall down from my eyes.

I don't deserve them! Specially Killua. No one really knew but I've been loving him since the first time we met at the Hunter exam and that was six years ago. 

A lot had happened then. Going to the Heaven's arena, finishing the game of Greed Island, fighting the Phantom Troupe, fighting the Chimera Ants, Gon meeting his father and many more. I was lucky to have them in my life but the time had come.

The time for me to disappear from this world.

Killua's POV

It had been three days since I last saw Kari and inside those three days, I've been doing missions to distract myself.

"I think it's time for you to tell her the way you feel about her." Kurapika told me on the phone and I sigh.

"But... what if she doesn't feel the same way as I do?" I ask him.

"Then let it be! Besides, you won't lose anything if you tell her the truth right?" 

"Yes I will, I will lose our friendship!"

"Then if the two of you are really best of friends, she'll understand and nothing will change."

"Fine fine, if you say so. But if she starts hating me after I confess to her, I will definitely hunt you down."

"Haha okay okay, but don't expect that you will eliminate me that easily."

"Whatever." And with that, I ended up the call. "Alright Kari, I'll see you soon."

I headed home to prepare myself and when I was about to leave, my pig brother stop me on the entrance.

"What do you want?" I ask him and he shrug.

"Well you know, since you're not always home I've been keeping your letters." He replied with a half smile.

"Whatever, do what you want with them, I couldn't care less anyway." I said and walk past him.

"Really? Cause it seems really important. Besides, everyday there's always a new letter from... what was her name again? Oh yeah, Kari!" As soon as I heard Kari's name, I turned around and pinned him on the wall.

"Where are the letters?" I ask him in a menacing tone of voice.

"And why should I tell you?"

"If you don't tell me, I will destroy all of your collections." I smirk and the colour on his face disappeared.

"Here here! You could destroy everything except for my precious collection!" He yelled while handing me about three letters.

Without saying another word, I left him behind and opened one of the letters.

Dear Killua,

I am sorry for not telling you this sooner but I am planning to leave. Not leave as in leave, but as leave the Earth for good.

Your best friend,
Kari

"What the..." I muttered and opened another envelope.

Dear Killua, 

I don't know how long I  would be able to survive but just to let you know, I am slowly dying.

Your best friend, 
Kari

"What is wrong with you?" I ask no one and opened the last letter.

Dear Killua,

Thank you for everything! I think this is my last day in Earth! Please tell the others that I will miss them, especially you because I... I love you!

Your best friend,
Kari

I widen my eyes as soon as I saw the last three words. Without wasting anymore time, I activated Kanmaru and headed towards Kari's house. I then felt my phone vibrated and check who the caller was.

"Hello Gon!"

"KIIIIILLLLUUUUUAAAAAAAAA! I'VE BEEN RECEIVING THIS LETTERS FROM KARI-SAN AND IT LOOKS LIKE SHE'S GOING TO KILL HERSELF! I'M TOO FAR AWAY FROM HER AND YOU'RE THE ONLY ONE WHO CAN AT LEAST KNOW WHAT'S HAPPENING!" Gon shouted on my ears and I almost went deaf.

"Gon! Calm down, I'm heading towards her place right now!" I said and ended the call.

Not long after, Leorio was calling me.

"What do you want pervert old man?" I ask.

"THIS IS NO TIME FOR YOU TO CALL ME THAT! I WILL LET YOU OFF JUST THIS ONCE! THIS IS AN EMERGENCY! KARI HAD BEEN SENDING ME LETTERS ABOUT KILLING HERSELF! WHAT IN THE WORLD DID YOU DO?! I THOUGHT YOU WERE LOOKING AFTER HE-" I ended the call immediately.

Lastly, Kurapika called.

"I already know what you're going to say and I'm on my way there!" I told Kurapika and I heard him sigh.

"I trust in you." Was all that he said before he ended up the call.

A minute later, I was in front of Kari's house. I press the doorbell several times but no one answered. My adrenaline was pumping up as I don't know what's going on. Without thinking, I kick the door opened and was shock at what I saw.

Kari's house was a mess. Her things were scattered everywhere and there were broken glasses from here to there.

"KARI!" I yelled, desperately looking for the woman that I love without caring what I bump.

Soon, I ended up in her room. I opened the door to see Kari down the floor, cutting herself.

"KARI! WHAT ARE YOU DOING?!" I ask as I grab the knife off of her.

"K-Killua..." She loudly whisper before falling down.

I caught her just in time, her blood merging with my white top.

She's barely alive!

I immediately rush to the hospital and found a doctor. 

-----Mini time skip----

"I'm so glad that you're alive." I kiss the back of Kari's hand and scanned her wrap body.

Her left and right arm were full of cuts. If I didn't went in her house earlier, she would have not make it.

A week had passed and I've been visiting Kari on the Hospital. The doctor said that this was the day that she's suppose to wake up so I came earlier than usual.

"Hey Kari, do you still remember when we were both an assassin? We would always compete on who can kill our enemy first. Unfortunately for you, you never defeat me." I started talking just like what I always do.

The doctor said that it would be better if someone was talking about the past to her just in case that she'll lose her memories.

"And the we're both ex assassin." Tears were starting to form from my eyes.

"When you wake up, I will tell you how much I love you. The way your black hair would sway and how I always play with the purple tips at the end. You would always hide your left eye because you think that it suits you better but... I think you're much more beautiful when I could see both of your eyes."

"You are fun to be with, always sarcastic when it comes to fighting and a good listener. I always hate how you steal my chocolates because you're also a chocolate lover but I always love it when I try and take my chocolates back because I get to spend time with you."

"You were always kind and respectful towards the others. So... why? Why are you trying to kill yourself? Why didn't you tell me earlier that you're going to commit suicide? When you wake up, you are going to tell me everything whether you like it or not!" The tears were now falling and not long after, I felt someone wiping them away.

I opened my eyes and saw Kari awake.

"Kari!" I exclaim while putting her into a tight hug like if I let her go, she'll disappear.

"K-Killua! Can't b-breathe!" She choke and I immediately let her go.

"I'm so happy that you're alive!" I told her while kissing her forehead. "Now tell me why you are trying to kill yourself!"

"B-because... I-I... don't deserve any of you! I-I'm weak and p-pathetic an-" I cut her off as I smash my lip into hers.

"Look, that's not true." I told her as I pulled away. "You are the most beautiful girl I ever saw in this world and believe me or not, I think you're much more powerful than me."

"T-thank you Killua!" She yelled and hug me.

I was a bit surprise at her action but I hugged her back.

"I love you." I whispered in her ears.

"I love you too!" She said back and I smiled.

-----Five years later-----

"Shadow nen!" Kari yelled and I was about to get caught by the chains but I dodge her attack. "You won't get away with this! Shadow demon!"

Black wings appeared from her back and I know too well about this ability of her. It makes her faster and stronger and she can control people and also make them see their worse nightmare. This is her most powerful technique. 

Although the only thing that doesn't work on me was her ability to control people. She can never control me and the reason for that was because she cannot control the ones that she love.

So I have to take extra precautions!

She sent kicks and punches towards me and I either block them or dodge them. Although whenever I block her attacks, my Nen would decrease.

"Come on, you should at least let me win old man!" She yelled and I stick my tongue out.

"Not a chance!" I teased her and she pouted.

Her eyes then sparkled and she swipe my leg under, making me lose my balance. She then went on top of me and went closer to my face, planting a kiss on my lip and making my whole body frozen.

"Take this, Fire cage!" She yelled while flipping backwards.

Fire and shadows started forming around me like a cage and this was the end for me.

"YAY! I FINALLY DEFEATED YOU!" She jump up and down in joy and it took me a while to process what just happened.

"Hey, not fair! You trick me!" I exclaim and she stick her tongue out while making her fire and shadows disappear.

"Yeah yeah whatever, just admit that you liked it." 

"Whatever, I will never steal your *favourite food* ever again." I stated and I grab her wrist while pulling her towards me.

"Yeah, if you don't want to experience defeat again!" And with that, I kiss her and she kiss back.

We both kiss each other passionately and separated, our foreheads touching each other.

"I love you Kari."

"And I love you too... Killua!"

Hope you like that and sorry for the long update!
