Junko (Li Qinger), an overseas Chinese in Japan, came to Korea as an exchange student for her secret boyfriend. I thought that the sweet home where I came to live in Korea would have friendly hosts, delicious food, warm rooms and so on. However, in order to keep Junko, the owner even gave his son's room to Junko, and the completely unaware son returned to his room as usual. Junko started to get into trouble on the first day of his life in Korea. Seeing Junko leaving home, the master tried his best to keep her. He not only gave up his son's house, but also asked his son Zhong Wan (Ki-wong Park) to give her one-on-one Korean tutoring.

Uncle, the shopkeeper with a bean curd knife, threatened his son Zhong Wan and had to be Junzi's Korean extracurricular teacher because of too many credit card debts. Although Zhong Wan is handsome, she is not good at learning Korean at all. Besides swearing, he has many bad habits.

Junko is full of hopes and dreams for South Korea, but her road will never be so smooth.
