Transcendence Multiworlds

Nova Wisconson was the daughter of a rich couple, and was the only child of said couple. But, disaster struck. Her best friend betrayed her for some man, so her company sunk and she was murdered in cold blood. Now, bound to a cheery system, her goal is to finish off 10 worlds so she can go back to her own. Of course, no one said that having a lover who would follow you was easy, especially for her.
