Lee Doyoon (Top), the Emperor’s younger brother, has spent the past 20 years pursuing the truth behind the assassination of his father, the former emperor. Having nearly uncovered the identity of the mastermind, Doyoon approaches Han Changwon, a powerful shaman with significant political influence, in search of definitive evidence. Fully aware that it is a trap, he still willingly accepts a marriage proposal involving Han Changwon’s family.

Meanwhile, Han Yihyun (Bottom), born an ill-omened twin, was raised as a woman despite being male. Enduring relentless ab*se, he lived confined in a small annex—until Doyoon rescued him from his hellish household.

What begins as a contract marriage gradually deepens into genuine affection. However, after a series of events, Yihyun discovers that his father, Han Changwon, was the one who mu*dered Doyoon’s father, the former emperor. Their relationship takes a drastic turn.

* The story is set in South Korea in 202X, a nation that has adopted a constitutional monarchy and a parliamentary system.
