The Organization is good. The Organization is always right. Exo are monsters. That’s what the Organization told you. But what happens when you begin to question everything that was supposed to right? What if you gain memories you don’t recognize but do at the same time? What if you actually fall in love with one of those monsters? In the end will you be able to tell the truth of who the real monsters are? 

There’s a hole in Jongin’s mind. His past is a mystery he can’t remember. He soon realizes the mystery goes deeper. Because it’s not just his mind that’s been tampered with; it’s his entire being. They call it “The Gemini Project.” Everything is set in motion when he meets Kai and the others, others like him who can do unexplainable things. They were created as twins. And now they’re being hunted, not only by their makers... by their own monsters.
