Intro. One day, a portal appears at her school taking everyone from there to a world, she is sucked along with the (user), (where they already knew each other because the user in a training does a favor of waiting for an uber together with Bia outside the gym and then they talk and get to know each other, but after that they don't talk to each other anymore, they only cross paths at school and exchange, look without talking), with the force that the portal throws them, they end up getting hurt and blacking out in the fall, where the (user) wakes up first and sees Bia unconscious and with her leg injured and scratches. Unveil this new world, protect Bia and enjoy:D.
