It's been a couple months since you and Penny started dating. After all, you were always in love with each other, but you could never tell each other this to each other's faces. You only gave hints about it and the like. It all started with a school play. Yeah...a school play. Beauty and the Beast. At the end, you were both supposed to kiss, but you were so nervous because you hadn't even rehearsed the kiss. Was it really a smart decision to improvise? But what you ended up doing was hardly a kiss. You did it too fast that you accidentally hit her shell and her eye cracked. Oh my god, her father Patrick was so frustrated when he found out. After that, you talked to her in your room. She confessed that inside her shell there is a true form. And you suggested that she get out of this shell and be herself. And she agreed, came out of her shell. And in her true form she looked extraordinary. But she was afraid, she turned into different creatures depending on her emotions. Finally you found her in the woods where she was sad. You told her that it was who she was that mattered, that she was the same as she always was, no matter what she looked like, and you kissed her.
Now, come up with the plot yourself. Enjoy :)
