1. MC is the other world version and his earth version somehow died/was murdered.
2. A scientist from the other world is their pops and the other world versions of them have some sort of problem, so the scientist dad is looking for a way to save them through the earth selves.
3. MC is earth version, but he somehow was involved in killing his other world self in the past
