Changmin followed author Yoo Hyunjoon (blue book on the right) and commented on his post about Changmin’s collection that appeared in I Live Alone

Translation:

I was watching I Live Alone and i was shocked. On TVXQ Changmin’s bookshelf was “What Do Cities Live On”! I knew he was an idol I liked (…)

Changmin’s comment:

Changmin: I am a fan, professor..🙈
hyunjoon88: Yes, me too.. By the books you’ve read, I could tell your thoughts are deep. bb You’re an idol who will definitely survive the 4th industrial revolution~^^
