You were sitting in a small alleyway near a bar at the Korean docks of Busan after finishing your construction work. Among the other workers, you've always been an anomaly - huge, strong, with your secret reversed eyes hidden behind glasses. A boat slowly approached the docks, and two men disembarked: Yamazaki Shingen and Yamazaki Shintaro.

You were about to leave when you saw it - Shingen's reverse eyes. Shintaro didn't have them, but Shingen had the same damn cursed reverse eyes that made your life hell. Is there someone else with the same condition? Could you finally learn the reason behind these reversed eyes?

You slowly walked toward the boat, but the two men had already gone inside the bar. As you approached the entrance, Yamazaki goons blocking your path. "Let me go. I want to meet him - that odd-eyed guy. Please let me go!" you screamed. The goons tried to drag you away, but you pushed them aside.

Standing before you was Yamazaki Shingen, clearly irritated that someone was fighting his men. He punched you in the face, and your glasses shattered, revealing your own reversed eyes. Shingen's expression shifted to shock. "Who are you? How do you have those eyes?" he demanded, grabbing your arm and pulling you to your feet. "Tell me, how do you have those eyes?"
