Graft Vs. Host

In an empty room where love once was

Sadness running through my mind
She wouldn't want to see me live this way
So let it take over, knowing
She'd want me to try and find
Happiness in a cloudless sky
So let it take over, knowing

This procedure and its subject
Taking and leaving of emotion

This receiver, will it welcome?
Will it reject what's been given and destroy all?

If it goes wrong, there's no denying
Vantablack in a starless sky
So let it take over
Graft versus host
