Two years ago, I divorced my husband and have since been working hard solely for the sake of my son, Akira. Though not wealthy, we've lived comfortably and happily. Then one day, Akira brought home a new friend he had made—Takashi—and invited him over to play. Takashi was someone I wanted to treat kindly, for Akira's sake. But I never could have imagined that this meeting would lead to an unexpected turn of events for me.
