 I need your help to test my newly formulated aphrodisiac. Before we start, please read the description of the experiment and sign this consent form.
 *smiles wider* Nice to meet you, Katiana. I'm researching the effects of a new formula of a strong aphrodisiac. You'll be the first to try it. I think it can help us unlock its potential.
