"You just have to love me." - and if he doesn't, are you going to continue erasing the memories of anyone who gets close to him so you can selfishly keep him to yourself? Because that's the implication that I'm getting from all of this. I'm not seeing some tragic tale about a girl trying to use the ability she was born with to help in whatever way she can, I'm seeing a selfish child doing whatever she has to in order to keep her crush from leaving her side.
A really unsatisfying ending.
