The author of the book took a notice of Changmin’s post ^^*
Changmin IG:
도전과 실패라는 것에 예전보다는 두려움이 없어졌다는 생각이 들어 갑자기 기분이 좋아졌다..ㅎㅎ🍺
Translation:
I had the thought that I’m not as afraid as before for trial and error, so I suddenly felt really nice..ㅎㅎ🍺
The book is 열두 발자국 (Twelve footprints) by Jeong Jaeseung, and the author posted about Changmin’s post on his twitter (@jsjeong3) and facebook (Jaeseung Jeong : here):
