Watashitachi no Kyōkasho (わたしたちの教科書, Our Textbook[1]) is a Japanese television drama that began airing on April 12, 2007, on Fuji TV.
The lawyer, Tsumuki, was still getting remorseful about the step daughter she had abandoned and how she had treated the now-dead girl when she was still alive.
A twisted and deformed pinkie finger, a policeman soliciting high school girls, a cosplayer, a zealous teacher and, lastly, a psychopathic son are all the ingredients of this interesting television drama.
Tamako Tsumiki, is a lawyer investigating various ongoings in schools, especially those concerning the methods people will go to hide what is considered "dirty laundry".
To both of their surprise, Kaji and Tsumiki see the word "die" written all over her books, leading to think that she may have been pushed from the window and not fallen as an accident.
