Tomorrow(2017)

Naeil

Jun-Ung, an unemployed college graduate, slips into a coma when he accidentally falls off of a bridge. While he's in a comatose state, he gets an offer from the crisis response team of the underworld company Flashback to temporarily join their team. If he accepts this offer, he could wake up early from the coma and even get rid of the karma from his past life that’s been holding him back from getting jobs! He’s got nothing better to do tomorrow, so it’s a beautiful day to save lives… with these grim reapers!!
