Ep 2

• Student boy's peculiarity is with his feet ( in the webtoon it's on his back of his head caused from injury)


Ep 3
• Detective Yang has bigger role in series ( appeared only once in webtoon, he was already a grim reaper, more of it later)
• Kim Sanghoon is a new character
• Sergeant Mun is also introduced in the series but has bigger role in Bridge ( Moving sequel webtoon)


Ep 4
• Bus driver in the elevator ( in the webtoon,  the accudent was caused by 2 car collision and it was the truck driver's fault. The bus driver doesn't have a role in webtoon but the truck driver does)


Ep 5
• Jiyeon is deaf before she died ( there is no indication in the webtoon that she was deaf)
• Young boy inside the bus during the accident ( the boy was not the webtoon)

Ep 7

Ep 8
• Hyunjoo's mother gave her a bulb ( Hyunjoo willingly goes to light shop)
• Nurse knows about the light shop ( not indicated in the webtoon but she could see ghosts)

The series didn't show Hyunjoo's peculiarity, Hyunjoo's face doesn't have any shadow. The light shop owner put a light on Hyunjoo's face and that's when he saw Hyunjoo's strangeness

Detective Yang's cameo in webtoon - he entered the light shop, he and the owner knows each other and detective is already a grim reaper. He rant how tiring their job is but the owner just said its their job and detective left the shop with a box full of broken light bulbs

grim reaper detective was just an easter egg in webtoon.
