The "Hi! Korean Series" is an integrated Korean language coursebook designed for foreign learners who are interested in Korean culture and have begun studying Korean.
The textbook incorporates the latest trends in Korean culture and offers a variety of activities to help students master the four areas of speaking, listening, reading, and writing.

It organically presents speaking, listening, reading, and writing areas while maintaining a consistent structure from beginner to advanced levels, and it is structured so that listening and reading are presented separately for each subject to increase learning concentration by area.
In particular, in the step-up course, which moves away from problem-solving-centered activities, communication skills are developed by expanding what has been learned through speaking and writing activities.

The overall composition of the 『Hi! Korean Series』 is 10 Student Books (4 beginner, 4 intermediate, and 2 advanced), which include a separate 'Grammar and Vocabulary Study Book', and 10 Workbooks (4 beginner, 4 intermediate, and 2 advanced) sold separately.
"Hi! Korean 2A" is the first book in the series, designed for those who have completed Level 1 and are beginning to study Korean in earnest. It covers Level 2 grammar and vocabulary within the context of Korean society and culture.
In particular, by learning expressions related to public affairs that students encounter during school life, students can apply them effectively in real life.
