Definitely one of the best pieces of literature I've ever stumbled upon on. It was the like feeling I got when I read Tuesdays with Morrie. I could relate to many of the students here in this series and their problems, and it made me think if only I had met a teacher like Takayanagi-sensei. Haaaah. I would probably read this again and again.
