Twice disappeared

My name shall remain a secret until I have done what I need to do. Only then will I tell you, and by then you'll realise you know me too well.

You all know who I am, but not as the man who kidnapped his sister, not as the man who tortured her. Or stalked another girl.

But as the man who had too big of a heart to do such a thing. You will deny knowledge of my actions because you know me as a boy who loves.

Not one who hurts.
