Help me plzz... so i need to come up with a short story with a plot >>?

Why not write from the perspective of a geek. The first day of college was rather difficult for him, and that's when he started becoming crazy (he was tired of all the bullying collected from HS). So the next day of college, he became this cool dude. Every girl melted like butter under the sun whenever he passed the halls. And every girl he dated, he secretly murdered. Then, this other geek in school comes, solves the crime of the missing girls, and problem solved. However, the people thought that the good geek was the real killer, so he was the one sent to jail with a death sentence for brutal murders, while the bad geek claimed that he tried saving each girl from the "jealous" good geek and was hailed the hero. In the end, he stops killing women, but continued his life as the cool dude (he's wealthy now), thanking the dead geek (for his clumsiness) in the grave and his first day of college.
