Plot one: A familiar curse has taken hold of an Heiress to the Castle of Greenbriar. After turning away a sickly looking old man from seeking shelter in her home, he revealed himself to be a powerful Wizard. Angered by her shallowness he cursed her with the same curse his own sister had used on a man hundreds of years before. He transformed her into a Beast of his own making. Now trapped in her home, she has only one night a week to be her true self. Unless freed from this curse before her thirtieth birthday, she is doomed to remain as a Beast for the rest of all time.
(This can be set loosely in modern times, or the past.)
*This plot is loosely based on the stories of The White Cat & Beauty and The Beast
Plot two: They met on the seashore after a terrible storm. They met in a burning building. They met during the war in the medical tents. They met in a restaurant. So many times they have met, so many times he as died. And every time one dies, one lives on. Longing and lingering. Sometimes he remembers, sometimes its a new beginning all over again. But every time, the lover looks the same and every time they fall in love. However this time when they meet, there is something different. He/She is already dating someone else, and it looks serious.
*The genders can be different. I don't have a preference on the immortal or the reincarnated.
Plot three: Lock ins are always a blast. It doesn't matter if it's in a gym or a classroom, as long as your friends are there you're bound to have a great time. Except, this time it wasn't voluntary. A routine trip to the aquarium resulted in you once again clonking yourself on the head. For some reason this particular time you were knocked out for a good three hours, and no one found you. Now that you're free from your hiding place, you remember the aquarium is closed for the next three days for (a major holiday/road construction/bad storm) and you're trapped. Since no alarms are going off you decide to investigate. They don't show you everything on those behind the scenes tours...
*This one involves a mermaid being part of the aquarium, which I would prefer to play.
Of course, I will probably add additional plots as I come up with them. I'm tossing around a weird idea involving a woman cased in Jade, a Princess gambled away by her father to feed his terrible habit, and a Barbarian king with a soft spot for flute music and small birds. I'm not quite sure where it's going, but I'll let you know. I'll use whichever medium you like to tell the story.
