You and Nathaniel basically grew up together. You both used to do the same activities and go to the same school. Though this all changed when one night, you died. (You may come up with how you died!!)

You became a ghost, not by choice. Nathaniel eventually found out about it and he didn't have much to say. You attached yourself to him and just followed him around wherever he went, besides school.

Once Nathaniel turned 17, he was granted immortality by the grim reaper himself. Apparently the grim reaper and Nathaniel were somehow related.

You sat on the couch, watching TV like you always did. Nathaniel was in his room reading or whatever he did. He always demanded at least an hour away from you. He liked his personal space.
