The Space Between

Kang Tae Hyun's life was forever changed when he got into a car accident. As he hovered between life and death, he found himself in a mysterious realm. A White Dress Girl appeared, offering to take him to "Haven," but Tae Hyun refused, worrying about his wife Ki Hoon's distress.

Undeterred, the White Dress Girl directed Tae Hyun to a path where he'd meet someone who could help him return home. Instead, he encountered the enigmatic Red Dress Girl, who claimed she could send him back - but only after sending one of his personalities first.

Tae Hyun agreed, and when he woke up in the real world, he was greeted by Ki Hoon. But their reunion was complicated by Tae Hyun's new, more dominant personality, which caused tension in their relationship.

As Tae Hyun navigated his changing dynamics with Ki Hoon, the Red Dress Girl reappeared, revealing a shocking task: help a man from a parallel world, Menworld, love his wife. The catch? The man was identical to Tae Hyun, sharing his name and face.

Now, Tae Hyun must confront the mystery of parallel worlds and the Red Dress Girl's true intentions. Will he succeed in helping his parallel self, or will he become trapped in this new reality?
