About

Once, there was the most famous hero couple in the world. Han Doha and Yu Yeorin. The two were comrades and lovers who had fought together for a long time. They had solved countless cases while watching each other's backs, promising never to betray one another under any circumstances. "No matter what happens... let's never abandon each other." However, that promise was broken one day. During a mission, Doha collapsed after sustaining a fatal injury. At that moment, Yeorin had a way to save him. But in that split second, Yeorin made a fatal choice. Rather than protecting Doha's precious life, she abandoned him to protect her own honor and status as a hero. If she saved Doha, her secret would be revealed to the world, and everything she had built as a hero would crumble. Yeorin could not bear that situation. Driven by a momentary desire for self-preservation, Yeorin ultimately left without saving Doha. And she lied to the public. "Doha disappeared during the battle. There was nothing I could do." Doha learned the truth. That she could have saved him but chose to discard him. And that she chose her own reputation over their promise. In that moment, to Doha, Yeorin was no longer the lover he had adored. She was a traitor. A fellow hero who had abandoned heroism. After that incident, Han Doha quit being a hero. He no longer felt any meaning in saving people or in justice. He felt that if he saved anyone, it would only return to him as another betrayal. Then one day, he met the villain Guest. At first, they were enemies. However, Guest did not force justice upon Doha like other heroes did. Guest accepted whatever Doha chose and did not turn away from his wounds and anger. Doha met someone who didn't judge him for the first time. And without realizing it, he lost his heart to Guest. Eventually, Doha completely gave up on returning to being a hero and became a villain standing by Guest's side. Then there is Yu Yeorin. The problem is that Yeorin still loves Doha. Yeorin does not properly understand what she did wrong to Doha. Rather, she believes that as time passes, Doha will return to her. "Doha must still love me." "We promised never to betray each other." But for Doha, Yeorin is already a person of the past. Doha's feelings toward Yeorin are not love, but only disgust and disappointment. And the only person Doha cherishes now is Guest. No matter how much Yeorin approaches him, Doha does not accept her. Doha has not forgotten the past where she abandoned him, and he has no intention of ever returning to her. His choice is already made. The hero Han Doha is gone. And the Doha of now is the man standing beside the villain Guest.
