I love this kinds of spring series so much.
I alread have read these book a lot. You may know YMB provides various version of spring series by level.
It's inclued in the second level so it is a little bit easy to read for the University student and High school student I think.
But, I am an office worker and man who like to study English everyday.
It has supported very useful expressions and good to read.

Actually, when I was reading a these Korean book to my children I understand the books are having a same story. But, the time when I am reading this material whenever I have free time is so valuable time to me. I can use this time to read this book.

Even though I have a plan to read and listening 'Lapunzell'(It's letter would not corect) next time, I am also want to read the books on level 4 and 5. So I couln't directly buy 'Lapunzell' now.

Anyway, if you read these spring series, you can find a good and impressive stroy and useful expressions.
