Getting a special person

Y/n pov-

I walked outside with my bags and bid my farewell to everyone , a man a very tall , was waitnig for me with a bike

???- are you y/n ?

He said in a gruff voice

Me- Indeed I am , and who might you be?

???- names hagrid

Me- nice to meet you hagrid

Hagrid- same , so you got some time 

Me- why?

Hagrid- you see , Dumbledore has given me an assignment of accompanying a boy to hogwarts , since his family doesn't support it

Me - what is the boy's name

Hagrid- harry potter

Me- very well then

We then got on the bike

Hagrid- hold on

He then revved up the engine and the bike started to fly , I sat behind him

We started to enter a stormy area and saw a cabin on the shores

Me- say hagrid , do we need to only talk  or kill them

Hagrid- we tried talking to them but it didnt work so we only need to scare them

Me- then leave it up to me

Hagrid- ok?

Me- you seem unsure in my capabilities

Hagrid - well in my defense we haven't been told about you anything yet

We then landed on in front of the cabin

I went up and knocked it twice 

No one answered

Me- good

I then kicked the door down and we entered

I was greeted by four people 

A skinny boy , a fat one, a fat man and a thin lady but with a long neck

Me- judging by your state 

I said as I walked towards the skinny boy

Me- you are harry potter right?

Harry- y-yes sir, w-who are you?

The fat man- YES!!! WHO ARE YOU!?

In a flash I was in front of him and he was in the air as I lifted him by his neck 

Me- who do you think you are , speaking to me in that tone?

Just then the woman shot at me

???- LEAVE MY HUSBAND ALONE!!!

I just caught that bullet with my mouth and looked at her

I crushed the bullet 

Me- you saw that right hagrid, they attacked me first

I said unsheathing my sword as I dropped the man

I walked towards the woman and glared at her as she fell to the ground

Me- Dont get too cocky..........inferior bastard

My pressure made her faint

The fat man- PETUNIA!!! YOU WHAT DID YOU DO TO HER

Me- self defense

I walked towards harry and offered him my hand

Me- lets go , my boy

Harry- yes!

He took my hand as we went outside and sat in the sidecar

Me- like I said stay in your line

We then flew off
