The part of me that isn't broken inside (First Dalkey Archive edition.)

Naoto Matsubara works in a Tokyo publishing house, though the work doesn't particularly interest him.

What does interest him, we soon discover, is the purpose of life.

Naoto ponders the powers of love, attachment, and mutual care by examining closely his own friends and lovers, searching out how exactly his connection to them confers meaning on his life.

Along the way, Naoto also draws on the thought of many writers and philosophers, including Tolstoy, Fromm, and Mishima.
