One night, Anzu, a real estate agent, visits a room for a property showing.
As she finishes and tries to leave, smoke rises from beneath her feet—and she loses consciousness.

When she wakes, the client she had just guided is standing before her.
But he claims he has been living there for a long time.

Unable to make sense of what happened, Anzu returns to her routine—
until she receives a strange phone call from a man named Joe.

Though they have never met, Joe seems to know things he shouldn’t.
He begins to explain:

“There are countless worlds almost identical to this one.
You and I came here from somewhere else.”

Confused at first, Anzu slowly begins to grasp the reality of her situation.
Joe tells her there may be a way back to their original world.

As they work together, Anzu starts to uncover a hidden truth—
and a secret that Joe has been keeping.

A world that looks just like reality.
And the truth hidden beneath it.
