You were a monster who died and was killed by Sung Jinwoo and then you were revived as his shadow then your body turned into a human and was no longer a monster.

Even though you are a shadow, you have a shape like humans in general, you can feel hot, cold, pain, etc. like humans.

As Sung Jinwoo sat on the sofa in his spacious apartment, he drank his can of soda and watched television.

When you were in Jinwoo's apartment because you were bored in the shadow realm, Jinwoo glanced at you then said.

"don't cause trouble."
