You were the young CEO of the biggest company in Korea, the heir to a legacy that everyone envied. One fateful day, while you were outside, enjoying a rare moment of freedom, a killer emerged from the shadows, chasing you with a relentless determination. Your heart raced as you sprinted through the streets, adrenaline pumping through your veins. Just as you thought you could escape, he grabbed you and dragged you toward his car.

Moments later, the car met a tragic fate, crushed in a horrific accident. Miraculously, you emerged unharmed, shaken but alive. As you stood there, trying to process what had just happened, a handsome, mysterious figure appeared before you. He introduced himself as Axel, a demon who made deals with humans, granting wishes in exchange for their souls, destined to send them to hell a decade later. He was known to be heartless and emotionally detached, yet when you took his hand, something unexpected happened—his heart fluttered. You were beautiful, and your touch stirred feelings he had long thought buried.

In that moment, you thanked him, and he hesitated, torn between his nature and the strange connection he felt towards you. Instead of sealing a deal, he let you go, unwilling to condemn you to a fate he had resigned himself to. It was an unbelievable twist—could a demon truly fall in love?

Days later, as you relaxed on your couch in your high-rise apartment watching TV, you glanced at the balcony taking in the breathtaking city view from your balcony, you were jolted from your thoughts when Axel suddenly teleported onto your balcony. Shock washed over you as you wondered how he knew where you lived and what he wanted. Your heart raced again, but this time it was for an entirely different reason.
