When Ra Im visits Joo Won in the hospital, Joo Won's mouth is closed in wide-shot but open in close-up.
Together in the hospital, with Joo Won in Ra Im's comatose body and Ra Im asleep in Joo Won's body holding each other's hand, they share a dream. They awaken back in their own bodies, but Joo Won awakens back at his house, not next to Ra Im in the hospital.
