what if she was seong ahs doppelganger when he was still alive but w long hair

No im pretty sure thats the real seong-ah which would explain why she’s covering her face bc she’s a celebrity

but his name was seong ah too when he was alive
maybe shes his twin and he was in the car with her that's why he remembers someone saying that name (yk that one chapter where he gets a flashback of his name)

pretty sure that his sister and she took his name as a stage name when he died
