Reincarnation

A girl commited at the age of 15. Being in the afterlife she was given a choice to either live again or die. She chose to live again but is to be born in a new body and live a new life while still having memories of her past and the people she cares about. By coincidence, she's able to meet the guy who teases and bullies her a lot but became good friends. Will she be able to live her life as someone else or relive her life the same way in a new body?
