I think they're both going back in time to when each of them are about the die. Sunwoo goes back in time to when Gajun gets swallowed up by the monster or sometime before that...Then Gajun of course goes back in time to the bus scene.That just makes sense as to why Sunwoo is so sure with C-2 monster machine thing and why he's more unstable.This is a really good plot btw.
