I Was in a Psychiatric Hospital, Then Became a Second Personality!

Any Novels About Two Souls Sharing One Body? ♥

I'm looking for a story where the male and female leads meet, an accident happens, and one of them ends up living in the other's body as a soul, with their consciousness intact. One of them should be a genius, and later they should get a physical body. I read one like this, but it was too short. I really enjoyed it.
