Ye An, the exiled prince of Star Alpha, pretends to be a human and lives on Earth. He lives in a village in the city, eats instant noodles, and lives his life as the most miserable alien exile. On a rainy night, he was hit by a mysterious blue light, and was forcibly bound to the "Marriage First, Love Later System" - if the mission failed, the crystallization penalty would be triggered. Only by marrying a human woman and gaining 100% of his true heart value could he repair his energy core and return home!
The system has frequent bugs, and the glamorous auctioneer Su Li has been locked as the "ideal spouse" with a matching rate of 92%! In order to seize the α-star core stone (the key to repairing the system), Ye An transformed into an antique dealer and sneaked into the Obsidian Auction House. However, he was accidentally involved in the conspiracy of the auction house, the mystery of his mother's death, and even discovered that the Reaper Brood is approaching the earth!
A fake couple turns into a real partner, a system bug becomes an opportunity for counterattack, and the alien son-in-law joins hands with the keykeeper to break the auction trap, uncover the secrets of the home planet, and resist the Reaper invasion! When the Reaper fleet, which is a hundred times larger than the vanguard, attacks, can Ye An use the royal blood as the fire to unite the forces of the two civilizations and hold on to the last hope of the solar system?
