My husband is on a long business trip, and I am living with my son Ken. Although he has been raised to be kind-hearted, there is one thing that concerns me. That is, he never leaves his smartphone, even during meals or baths, constantly communicating with his classmates. And as soon as his grades started to drop, I decided to confiscate Ken's smartphone. This action, however, ignited the desires of Ken's classmates and brought an unimaginable tragedy upon us. At that time, I had no idea what was about to happen.
