Leanna is an ordinary delivery person who raised her son Shawn by herself. She thought her son Shawn was just a mischievous troublemaker who always came in last. Unexpectedly, the seven-year-old Shawn is actually a famous genius doctor in Lingzhou. Shawn pretends to be silly at school to hide his identity as a doctor. While Leanna was delivering food, she was saved by Timothy, who is actually the Iroln boxing champion and the man Leanna had a one-night stand with seven years ago. He is also Shawn's father.
