If he set his sights on a treasure, there was nothing he couldn't get his hands on. One careless mistake later, Lin Jinyue transmigrated to the modern day and became an idle rich heir who never applied himself. His childhood friend and fiance, Gu Zhiheng, looked exactly like the man who had caused him to fall into the sea! As the head of Changfeng International, Gu Zhiheng was decisive and efficient. He was unhappy with the arranged marriage, but on the very night he proposed breaking off the engagement, his fiance mysteriously drowned. When he woke up, he was a completely different person... There was no way Lin Jinyue was getting married. He devoted himself to driving his archenemy into bankruptcy, battling Gu Zhiheng to the death while returning to his old line of work and starting an antique business. With his sharp eyes, no fake could escape him. He fought his way to victory on the high seas, recovered lost treasures, and breathed new life into a family business on the brink of collapse. At the auction house, he was cool and composed, landing a decisive blow to save a priceless national treasure. After being named an Outstanding Young Entrepreneur, Lin Jinyue was invited for an interview. Charming and witty, with graceful, easygoing manners, he went viral as soon as the broadcast aired and became the dream man of countless people. Meanwhile, Gu Zhiheng, the rightful spouse, was left deep in thought as one rival after another suddenly appeared: 1, 2, 3, 4, 5... Even his idiot cousin joined in the trouble. "Bro, if you aren't planning to marry Jinyue, let me have him. If he marries you, he's my sister-in-law. If he marries me, he's your brother-in-law. Either way, we're family. The three of us can make a good life together!" Someone panicked and that very night, clutching a diamond ring the size of a pigeon egg, knocked on Lin Jinyue's door. - Everyone knew that the presidents of Huayun and Changfeng were a pair of bitter rivals who never crossed paths without fighting. Everyone was waiting to see when they'd get divorced. Then one day, a piece of gossip landed at the top of the business-and-entertainment headlines #CEO Couple Brawls at Banquet# Curious onlookers who knew nothing about the truth clicked on the video, only to see President Gu pinning his lover backstage at the banquet. One of Lin's legs was wrapped around Gu's waist, and he was tugging at the hair at the back of Gu's head, eyes hazy. "Kiss me." As soon as the words left his lips, the man kissed him deeply.
