My revenge?

Remember the day that you left?
my tears flow by threads,
you leave me with a deep stabbed
to which i cannot patch.

a months and years passed,
nothing's left but scars,
and your tattooed name on my chest
a name i can't forget.

i'm back for sweet revenge,
i'll drown you by your tears,
i'll let you bleed a lot,
as i take a piece of your heart.

it's him that i stabbed!
but why are you crying?
it's him that i stabbed!
but why am i bleeding.
