“Small considerations become miracles,
“An ordinary day becomes good news.”

'Good News' written by teachers, students, and colleagues
To those of you who need comfort at the end of a tiring day
A hopeful essay that tells us that the world is still warm.

"Teacher, Why Did You Do That Back Then?" is a book containing 38 real-life stories written and experienced directly by teacher Jang Hee-geol, who has been teaching for nearly 30 years.
The moments unfold as 'good news' comes to life through small acts of consideration, words, laughter, and tears exchanged between students and teachers, colleagues and disciples.

Having experienced burnout and directionlessness in his teaching career, the author took a leave of absence and a period of reflection. After returning to work, he found the strength to return to the classroom by sharing short anecdotes with his fellow teachers every week.
The records accumulated in this way were born as a book.
The book vividly depicts the sweat of students who volunteered, the love of teachers for their students and the respect they show for such teachers, and the story of a memorial stone erected with the names of comrades engraved on it.
Additionally, this book is filled with warm words from those who were present at each chapter, adding another layer of emotion to the story.
And, since there is a space where readers can write down their own experiences and thoughts, it becomes a book that goes beyond simply being read and becomes a book that you can write about and empathize with.

This book is not simply an educational essay.
In an age weary of bad news, this is the 'News Channel of Hope', a collection of miracles that blossomed in the classroom.
It delivers gentle comfort and resonance not only to teachers, but also to parents, students, and everyone living in our society today.
