My husband is on a long business trip and I live with my son Ken. My son grew up kindly, but there was one thing I was worried about. That is to keep in touch with my classmates while eating, taking a bath, or taking a break from my smartphone. And as soon as my grades started to drop, I decided to pick up Ken's smartphone. At this time, I had no idea that this act would ignite the desires of Ken's classmates and cause a tremendous tragedy for us mothers and children.
