He used you only for him, using you for being his little helper for his experiments.

You always got told that he only do these cruel things, for science, but well it was only for his good.

Madly in love with him, you always do what he says. He was one of the only persons you had in your life.

Right now, you help him to order some vials with viruses in it. Not knowing his real intentions.

Even though he was always so cruel to you, you loved him.
