A Special Klein of love

Knight of the Blood Oath!!

Me and Klein heard about how kirito is going to fight Heathcliff. Yeah the leader of the blood oath. Its probably cause of Asuna. But I have a wrong feeling about Heathcliff he reminds me of my father way too much.
"Hey Kat you want to go to watch kirito kick his butt."
"Yeah I guess."
"Whats wrong kitten."
"I am fine let's go."
"Whatever you say"
Time skip to battle.....
Kirito was fighting heathcliff and all he was doing was blocking wait no it can't be. His health isn't going down.
I know it is true now heathcliff is my father.
"Klein I will meet you after I talk to someone very important you go meet kirito."
"OK I love you."
I give him a kiss and left to meet my father.
Inside of the knights of the blood oath.
"Ma'am you cant go in there."
"I can do as I please."
"What is the problem out there."
"Sir this young lady wants to talk to you."
"Who is she?"
"The white Shadow sir."
"Send her in ASAP."
"Yes sir.' He turns to me." You may go in"
"Thank you" I walk away sticking out my tongue.
"Still childish I see."
"No I just don't like people."
"So not even you Klein friend."
I blush " How did you know about him."
"Your my daughter I know everything."
"I am not going to join your guild and I have a request if you log out."
"Yes."
"Change my last name away from Kayaba to Sora and transfer 20000 yen."
"OK so i won't see you again."
"Yes. At least until we have the end boss fight. Now if you don't mind I have a guild that needs me."
"OK good bye."
I walk out to see Asuna Kirito and so other knight.
"Hey guys who's the small fry."
"Kat how can you not notice your boyfriend's little sister."
"Haley your a knight. And you how stupid are you to fight Heathcliff."
"Thanks for the lecture what are you doing here anyways."
"Talking to Heathcliff."
"Wait he invited you."
"No I came uninvited. Yelled at him and left."
"Let me guess he wanted you to leave Klein's guild and join the knights. Something about you having a special gift."
"We all know I have many serects."
"Yeah that's true."
"So you joining us it would just be like old days."
"No no no. I would not be "like old days." I don't want to be anywhere near Heathcliff and if you don't mind I have people waiting of me."
I walk away to find Klein.
"Hey you just missed kirito in white."
"Ik I saw him."
"Where did you go."
"Places."
"Come on tell me."
"Why tho."
"Because you love me."
"Fine I went and talked to Heathcliff."
"You are not allowed to leave me for the knights. I won't let you."
"What made you think I would leave you?"
"You went to talk to Heathcliff."
"And that was all it was a talk."
"OK good i was so worried that you would leave me. I could never lose you."
"And you never will you would get yourself killed if it weren't for me."
"Your right you would but so would you" Lies i can't die.
"Yep I love you." He picks me up and spins me around "let's get married."
"What?" I said
"Kirito and Asuna did why not us."
"Cause its not real its a game Klein. You dont even know my real name ." I said and then I tried to storm off. The key word there was tried before I could get far he grabbed my hand and twirled me around.
"Your right I don't know your name but this is real I will change my real name to Klein if that would make you happy. Cause you are worth it. And I know that I am not perfect just look at me but I love you endlessly."
"Klein...,."
"Can't you stop talking and listen for once."
"Sorry."
"OK... Love only comes around once in your life. Life is like a swing and if you don't see it. The thing that was once in front of you is gone. In the blink of an eye. Everyone has their star and you Kat are mine."
"Katherine Sora..."
"What?"
"Katherine Sora is my real name. And you are my star too klein."
"Where's the but I know there's a but."
"But we have only been dating for almost two years are you sure you want to get married in the game."
"Yes I am dead sure and hey Jake can be our son like truly our son not the little boy who watches us go on dates."
"Yeah I will think about it."
And I got him to let go and teleported home where I had my own room. And messaged kirito and Asuna together.
To asuna and kritio
Hey guys so klein proposed. And I told him I would think about it. I mean I know you two did but try no secrets ruining it I mean I love him but what should I do.
To Kat
If you love him then why not. He really likes you a lot I mean he is in the inn crying so please make up your mind.
~kirito
To Kat
Yeah he looks really sad. Make up your mind fast for his sake.
~asuna
To Kirito and Asuna
Thank you for your words of wisdom.  But I think I am going to choose not to get married and leave him alone.
To kat
Whatever makes you happy.
That is my decion I am going to leave the guild right now. I clicked my guild thing and left the guild. I felt sad and knew it was time to disappear and become red. Not a red player but wear all but red. I left a note: Klien I know when you see this you will notice I left the guild also you would have notice that I am long gone. Just know that I love you and please take care of Jake make sure he doesn't die or come looking for me. you too don't die and don't come looking for me I am a solo player now.
And then I left.
Klein's POV
I was in the closes inn or "bar" that I could find when I notice I had a notification. What could it be. I looked at the notification and saw that it was a guild thing. The next words hit me by surprise Kat has left the guild.
"Klein."
"Yeah kirito."
"What happened."
"Kat left the guild I need to check the house maybe she is still there."
"Klein I don't think so."
"Why are you saying that i can't lose her not now we are on floor 57. We are so close."
"No klein were not and you went on and proposed so this is your fault that we might never see our friend again what in hell were you thinking."
"I was thinking that I loved her and that she would have wanted this too."
"I guess not."
"I have to go kirito before I miss her."
"Klein...."
"No kirito I get it.."
I ran to the portal and teleported to where our house was.
"KAT!!!!!!!"
No answer.
"KAT PLEASE TELL ME YOUR STILL HERE."
Still no answer I go to her room and see a note.
(Same note as before)
Jake walks into the room.
"Jake hey buddy."
"Where's Kat."
"Kat's not here she left us."he starts to cry.
"Hey buddy its OK its just you and me know. How about we show Kat how strong we are without her."
"OK Klein thank you." I was crying more now."klein its ok she will come back. We will see her again."
A/N
Little did they know she was right under that nose the whole time.
So in the next chapter I am going to write it to where we are at the meeting for the last battle scene in the first part of SAO and there will be flashbacks to the time that kat was away.
Leave a commit below on any ideas you want as a flashback also tell me how I am doig
