双O互换人生了！

In the final battle, Marshal Chen Wei heroically sacrificed his life. The Chen family was engulfed in flames, and his subordinates risked everything to save one of the Omega twins—the elder brother.

Eighteen Years Later

The elder brother, raised in the ivory tower, is refined and aloof. As the only heir of the Marshal, he is betrothed to the Crown Prince. However, the cold and distant pair have no sparks between them. Even their pheromones are indifferent to one another. Words like “superficial harmony” and “dreams apart in the same bed” seem tailor-made to describe their future marriage.

Meanwhile, the younger twin, rescued by a loyal servant in the underground city, has grown into the most alluring socialite. Every Alpha in the underground longs for a night with him, their jealousy simmering as they wait for someone’s wife to tear apart that stunningly beautiful face.

One Day, the Twins Reunite.

On a whim, the elegant prince’s consort dons a revealing backless outfit to visit the underground, while the flamboyant younger twin dresses in pristine robes and enters the ivory tower.

At dinner, the Crown Prince sits stoically across from his future consort, suddenly feeling an unfamiliar foot brushing his leg under the table, teasingly stroking it. The youth across from him props his chin on his hand, watching the prince’s every expression with lively, sparkling eyes.

That night, for the first time, they catch a whiff of each other’s pheromones.

In the Underground City

A gang of thugs, with ill intentions, gets slapped senseless and forced to the ground by an overwhelming spiritual force. The youth’s provocative attire contrasts sharply with the nobility in his every movement and glance.

An Alpha, exuding charm but clearly up to no good, asks with a smirk, “May I invite you to dinner?”

The penniless elder brother hesitates for a moment before gently placing his hand in the Alpha’s palm. “Your honor.”

Everyone assumes that the marriage between the Crown Prince and the Marshal’s son will inevitably fall apart due to their lack of pheromone compatibility. Young nobles eagerly sharpen their claws, dreaming of replacing him as the Crown Prince’s consort.

Yet, this same Marshal’s son—inseparably close to the prince and making others fail miserably at every turn—baffles them.

Younger Brother:

“When I was tearing apart green tea b*tches and white lotus frauds in the underground, you lot were still crying in the corner. And this? This isn’t even enough to amuse me!”

No one expected the supposed “useless” Alpha, cast out by his family, to have built an empire in the underground city. By his side stands a cold yet dignified youth whose overwhelming spiritual pressure inspires submission in all who meet them.

Underground Residents:

“What?! The flirtatious social butterfly turned out to be a ruthless, unstoppable king?!”

Double Couples:

• Dramatic / Carefree CEO / Optimistic x Emotionally Reserved / Cold and Distant / Fragile Doll (so to speak)

(An innocent duo trying to make ends meet)

• Repressed / Jealous Drama King x Scheming Top-Tier Green Tea Mastermind

(An emotional rollercoaster of morally ambiguous masterminds)
