7/10
During high school Maki-senpai kept kissing to give him salty caramel but also ignored him. Has been unable to get over that bullying, 10 years later on the way to senpai's wedding, Neo's thinking about taking revenge on him & gets car crash before waking up as a tiny spirit sitting on a highschooler himself
it turn out good and looks like senapi changed the past so he could change future.
