The Butterfly Of My Dream's

Noah, an unknown stage actor, is barely getting by while living with his younger sibling.
One day, while rehearsing with the troupe as usual, he notices a man he's never seen before.
At first, Noah assumes the man is a new member, but it turns out that only he can see him.
The man hands him a rosary, and upon touching it, Noah is overwhelmed by unfamiliar memories and accidentally drops it.
As the beads scatter in all directions, the man speaks an ominous phrase—

"Baek Noah, you're going to die soon."
