Bae Suzy plays Seo Dal-mi, who was admitted to university but did almost all part-time jobs after dropping out to earn more than 100 million won in opportunity costs. Because she started her social life at an early age, she has a wide network of contacts and good relationships. Not wanting to lose to her sister who married the second generation of a chaebol, she embarked on a difficult road with the dream of Steve Jobs. Nam Joo-hyuk will play Nam Do-san, the founder of Samsan Technology. He likes programming and won the youngest award in the Mathematical Olympiad when he was a child. He was the hope of the Nam family. Today, 15 years later, his family is broken. He started a business with his friends, and it has been 2 years since the business was established, but the investment funds have been wasted. This is the first combination of Bae Suzy and Nam Joo-hyuk. Just like the meeting of the two actors, the director and writer have great expectations. Bae Suzy is the third work after Park Hye-ryeon's "DreamHigh" and "While You Were Sleeping". Director Oh Chung-hwan has become a "heat maker" with the success of "Doctors", "While You Were Sleeping" and "Hotel Del Luna".
