Guess this cat!

I did nothing wrong yet she wronged me

I gave you my heart

And I thought I had yours

And now you are gone

I confessed how I felt

and oh the scars you made

About everything

Then you confessed to me

The secret left me shocked

Yet I didn't give up

I wasn't done with you

I never was

I would destroy you all

once and for all

the perfect little cat

would be the lying cheat

I never got the chance

The shadow stalked me

silent

it leaped and with one slash I was over

(cant tell if this is hard or not )
