Overtale, after Undertale (boy or girl)

Your a new face in a new neighborhood full of monsters, the kids at school bully you and treat you as an outsider.Its been a month since the barrier broke to our Overworld , and the giant battle of Asriel and Frisk. Grillbey opened a worldwide bar , Asgore, laying is crown down and opening a flower shop, Sans and Papyrus moving into a house after gaining jobs and the rest of the monsters live in the same neighborhood as you do . Then Flowey goes missing, you discover you have powers, and a BIG threat is coming to our world to take everyone and everything to smash reality forever..What can go wrong?
