It was less the fact of Yoshiko's defilement than the defilement of her trust in people which became so persistent a source of grief as almost to render my life insupportable. [...] Yoshiko's immaculate trustfulness seemed clean an pure, like a waterfall among green leaves. One night sufficed to turn the waters of this pure cascade yellow and muddy. Yoshiko began from that night to fret over my every smile or frown.
