Another Orihara- Shizaya fanfic

Chapter one:

Izaya's POV:
"Nissan, wake up my dear Nissan", I heard as I awoke to my hands being strapped to a banister inside my apartment.
I can't remember what happened after I saw him. Haruya, why are you doing this?
"Haru-chan, it's been a while huh, did you really need to tie me up", I asked with a smirk.
"Oh, trying to smirk your way out of this. Listen, you can pretend all you want to fool those ingrates, by I am flesh and blood, I know everything about my precious Nissan", he said with a similar smirk.
He reached in his pocket and took out a knife.
"My dear precious Nissan, oh how beautiful you are".
He cute the bottom of my shirt to reveal my pale stomach.
"So beautiful".
"We look alike Haru-chan, you narcissist. I'm you're brother, you twin brother, so why are you doing this, Haruya", I shouted.
"Oh dear Nissan, did I scare you, my precious Nissan, I'll never hurt you, I'll never hurt you ever, my precious, precious Nissan".
"Haruya, you've really become quite creepy, when we were younger, you were a lot cuter", I said with a sigh.
He put and arm around my waist, and his cold hand touched my side.
"Oh, Nissan stop looking in the past for me, when right in front of you, you have me, I want to make you mine Nissan", Haruya said with a smile.
"Haruya, you're obsessed this isn't love, it's madness. You're my younger twin brother, brothers don't have sex with each other, what the hell are you thinking", I shouted.
"My precious Nissan, is it that blonde's fault that your vision has become so cloudy"?
"Who are you talking about"?
"Shizuo Hewajima of course, Nissan, ooh I know, why don't I pay him a little visit".
"Heh, good luck, I would love to see you try to kill him. It would really save me the trouble".
"You can't hide your feelings from me, Nissan. You're in love with that brute aren't you".
"Just shut up, I'm not, we hate each other end of story".
"Aw, such a liar, my adorable precious Nissan", he said.
He let go of me and replace his jacket with mine.
"Don't worry Nissan, I'll make his death, quick and Painless".
"Don't do this, you'll ruin my life if you kill him, they'll lock me up instead of you Haruya", I shouted.
"I know, that's why, it's going to be fun", he said with a smile and he began to laugh.
He left me tied up still.
"Shizu-chan, please don't die", I thought.
Shizuo's POV:
I smell something, it's not the flea, it's something very sinister. I turned to see the flea smirking evilly at me. But something is different. Usually he would be waiting for me to find him. But this time, he's strange. There's a lot of blood lust coming from him.
"Hey Flea, how many times have I told you, not to come to ikebukuro", I shouted.
"My, my, it's not like you own this city, Shizuo-chan".
He said Shizuo, wait, his eyes are a different shade of red. Could it be that this isn't Izaya but, some look alike.
"Who are you"?
"Why I'm the famous, Izaya Orihara", he said.
"Don't lie, who the fuck are you? And why are you impersonating Izaya", I shouted.
"Heh, you saw through my little act of my precious Nissan".
"Are you his brother or something"?
"Yes, Haruya Orihara, I must kill you so that I can see Nissan's face in tears".
"Hey where is he"?
"He's in his apartment, but he's bounded up for the moment, Shizuo, anyway what gave it away"?
"As much as I despise that pest, there's only one name that he has called me, ever since I met him, with that annoying tone he has, he calls me Shizu-chan", I said proudly.
"Such a cute nickname, shall I call you it at your funeral", Haruya asked while holding two knives.
"Brother like brother, huh, both of you use those weapons that can really hurt someone, well a normal person anyway", I said while folding my glasses and grabbing the nearest street pole.
"Heh, heh, good, good, I wouldn't want you to die so easily, Shizu-chan", he said as he charged towards me.
I tried to hit him, but he dodged.
"Even though he isn't him, the way he fights, it's just like that bastard", I thought.
Meanwhile...
Izaya's POV:
"Luckily, that idiot left his coat right in front of me", I thought as I cut the ropes that were holding me with a pocket knife.
I squeezed my wrist as I saw the marks.
"That bastard better not ruin my coat", I said as I grabbed his and ran out of my apartment.
I hurried to where I heard a fight was going on, I had to help Shizu-chan, stop him. But why? I guess because I don't want him to be killed by my little brother.
I found them thanks to the people gathering around. I saw Shizuo  and Haruya. Shizuo had some scratches and Haruya didn't have a single bruise or scratch on him.
"Haruya", I thought.
I ran out and blocked his knife from hitting Shizuo.
"Nissan", Haruya said.
"Haruya, enough", I shouted.
"Izaya", Shizu-chan said.
"There's two of them", some people were saying.
"Haruya, you've gone too far", I said.
"Nissan, you know it isn't true at all, you want me to stop trying to kill the person you love isn't that right, how cute and noble, Nissan", he said.
I felt my face heat up a bit.
"Hey give me my jacket, you asshole", I said as I threw his at him.
He threw mine to me after taking it off.
"Hey, Izaya, what the hell is going on? Why is your brother trying to kill me, and why did he say you stop him from killing the person you love", Shizu-chan shouted.
"Shut up, you protozoan, now is not the time, Haruya has been playing with you, haven't you noticed", I shouted.
"Playing with me", Shizuo said.
"Nissan is correct, I haven't gotten the slightest bit serious, Shizu-chan", Haruya said
"If you don't want to die let me help you, Shizu-chan", I shouted.
