Five years ago, bottom-rung girl Chloe was framed by her vicious stepsister, accidentally spent one night with a mysterious tycoon, got pregnant, and was thrown out of the house. Five years later, she scraped by raising her five-year-old genius geek son Leo. Watching his mother bullied at work by his stepsister, protective Leo directly hacked into the core system of New York's largest chaebol, the Sterling Group, paralyzing the hundred-billion empire in an instant. Leo gave the cold CEO Alexander the sole decryption condition: go on a blind date with Chloe. Alexander swore to track down the mastermind behind the attack, yet during his "forced blind date" grew intensely interested in Chloe. What he didn't know was that the top hacker who had him completely under control was not only a five-year-old child, but his own flesh and blood!
