The Voided Heart - Sub!Leonardo X Reader

"This can't be real... I can't believe this.
Will my heart break, or will his?
Inevitably I will cause all of those sins
And then I'll repay by my life to an end!

It goes to show I don't deserve him
I am the cloud, and he's the silver rim
And I'm just tearing myself apart limb from limb
Yeah, I'm ashamed that my death will be all that grim!

Maybe it's best if I was gone,
And so I can let him live on
No drama, no bad qualities
Then his mind will finally be at ease

But I want you
I need you
My love, it's all true
Whatever I feel inside my heart
It's something totally new!

Oh I have seen what will turn out
Now I know what my love's about
It's all you
My love in blue
It's all true..."
