Bao Nam is a 21 year-old and good-looking guy. His favorite past times include partying, spending his parents' money, and more partying. One night while Bao Nam was drunk, he got into trouble with a local gang and was rescued by Truc. Truc is an 18 year-old, generous, and strong-willed girl who makes a living by selling used books on the street. Truc loves to be surrounded by books even though she is illiterate. Her dream is to save enough money so that she can open a small bookstore. Later, she was given a chance to realize her dream when Bao Nam's parents asked to make a deal with her - to teach their son how to become a decent and responsible person in exchange for money to open a small bookstore.
