Hanna has lived under the watchful eye of a conservative family, unable to even properly speak to her childhood friend and unrequited crush, Woojin. One day, a succubus with the exact same face as Woojin coincidentally appears in Hanna's dreams. Every night, she begins pouring out the feelings and desires she could never voice in reality. As the nights repeat, Hanna sinks deeper into sweet pleasure, and the boundary between dream and reality begins to blur... If reality is worse than a dream, Is there really any reason to wake up?
