Responsibility

Jack can have any girl he wants. Except one. The one he wants.

He's been in love with his chemistry tutor Candace since the day they met, but she's busy with schoolwork, too busy to date, and just doesn't see him that way.

So when a rival of hers approaches him saying he has a way to make her open to the idea, Jack doesn't ask questions.

Very quickly he wishes that he had. Candace is changing, and she has no hesitation in eagerly giving him, or anyone else for that matter, anything they want.

At first he can pass it off as harmless. And to be honest, pretty enjoyable. But when the effects don't wear off, and in fact seem to be getting stronger and stronger, Jack is forced to make some tough decisions, and take responsibility for his actions.
