Gu Nian and Lu Chen were tricked by their friends into getting a marriage license, and they simply signed a fake marriage contract. Both of them thought the other was really poor, so they tried their best to save money to subsidize each other, but the more they helped, the more their secrets were revealed - he changed the contract casually like changing an essay, and she solved technical problems in seconds like drinking water. The heroine who made a phone call in Russian on the balcony late at night, and the hero who accessed the darknet system in the early morning, looked at each other and said "I came out to drink water." The more you try, the more frightened you become, and the more you conceal it, the more excited you become. Until one day, the two bumped into each other at a high-end cocktail party and stood on the center stage - the one who said he worked in a convenience store was the CEO; the one who said he was delivering express delivery was a business giant. Their eyes met, and the air froze. This disguised marriage finally couldn't be hidden anymore.
