[Two male leads + Happy ending]
Ye Jin, crown prince of the Asura Clan, has an undying soul. After his body is destroyed, he falls into a small world within the vast multitude of worlds, where he is also pestered by a little demon claiming to be a System.
The crown prince has nothing better to do, so he decides to stick around and have some fun.
Unfortunately, his new body's former owner was not only a notorious good-for-nothing, disowned by his family, but also a man who liked men and had willingly thrown himself into becoming someone else's substitute.
And the person who treated him as a substitute was the chosen one of this small world.
Ye Jin figures it's no big deal. So what if he's the chosen one? Crushing him is easy enough.
But before he can act, Xia Lingzhou, the original love of the chosen one's life, appears before him.
The System asks: "Honored Host, should we take out the protagonist's one true love too?"
Ye Jin's eyes grow wide with hearts in them. "What protagonist's one true love? That's obviously my wife."
The System: "Host, we need to focus on our career!"
Ye Jin: "I know, I know. Focus on getting my wife!"
Xia Lingzhou: "..."
If someone asked Xia Lingzhou what it was like to be hounded by a madman, he could give a textbook-perfect answer.
But later, he must have gone mad too. Otherwise, how could he have found that madman so adorable?
