Geun Jungwon is the most famous successful and well-settled businessman. Geun Eun-Hee is also known as a famous surgeon. After completing their university they got married and continued their careers. They were happy in their little world but one-day Eun-Hee met Seon Soon-Ja who was attempting suicide. Eun-Hee saved her and brought her into their house. Jungwon wasn't happy with Eun-Hee's decision as he felt something weird toward Seon Soon-Ja but his love for his wife more than anything. Jungwon respected Eun-Hee's decision and agreed to let Soon-Ja live in their house, and then something changed all of their lives, something which they never imagined.
Kang Jungwon lived his life hating heroes. No matter fictional or not, he hated it. Not because of the recognition, nor was it because it was true. It was because Kang Jungwon himself was branded a hero, living a life closed to shackles and chains. Being called a child-hero of South Korea made him exposed to the outside world's harshness. It wasn't until he broke free, changed his identity, and lived a normal life that he began to finally love life. But then, he was put in another world and was stuck in a hero prophecy. It was his past all over again. But this time, he was committed to break free from the hero choosing and live a good life away from their eyes. And what better way than to let the story crumble? let the villain, him, escape, and let the protagonist, his brother, live out the life he originally wanted. Thus, Jungwon the anti-hero began to strike the plot's head.
