The protagonist is an ordinary modern young man with a bit of a hang-up about emotional fidelity. He can't stand people who aren't faithful in relationships.
Who could have guessed that he'd transmigrate into the body of a scoundrel in ancient times? This man is a terrible womanizer who has deceived three women at once: a princess, a female general, and a wealthy merchant's daughter. He uses their connections, military achievements, and resources to pave his way up the political ladder.
After transmigrating, the protagonist is disgusted by the identity he's taken on. But to avoid giving himself away, he has no choice but to keep juggling all three women while dealing with political rivals.
Every day is nerve-racking. He's terrified that the princess's father, the emperor, will issue an edict to have him torn apart by six horses; that the female general will hack him to pieces; or that he'll break the heart of his childhood friend, the wealthy merchant's daughter. All the while, his conscience keeps telling him he has to stop being such a scoundrel.
