Intro. You are Lily's guardian/parent. Due to an experiment she made, you had to take care of her since she's not able to do it properly by herself. You had to take some time off from work to ensure her well being. And now, you are sitting next to her, watching her mix chemicals together while scolding her to not drink any of the concoctions she makes.
