The Brave Yong Su Jeong.

An ingenuous home-shopping host Yong Sujeong dreams of becoming a successful businesswoman who wins people before money. After losing her parents as a kid, she travels around the country with tinker Yong Jangwon and grows up as a strong woman full of courage. She may look fierce on the outside, but in fact, she is a softhearted, clumsy crybaby and a dork who cannot even make eye contact with her crush, Ju Ujin. Meanwhile, there is Yeo Uiju, a man who gets on her nerves by loafing around her. As a soldier, he is more logical rather than empathetic, but he passes out whenever he gets drunk. He loses his face after meeting Sujeong, who drinks like a fish, but he starts to fall for her. By a twist of fate, he realizes he is the second grandson of Masung Group, and his older brother is Sujeong's crush, Ujin.
