Chapter 1

My ten-year-old son joined the school's extracurricular swimming club, but during practice, a classmate held his head down forcefully against the drain.

When I saw the water turning red, I frantically pulled my son out.

But his entire face had been disfigured by the powerful suction. He coughed up a pool of blood and stopped breathing.

The ringleader, a boy, shouted that he was a minor and not bound by law.

"So what? I've had it out for him for a while. With him dead, no one's competing with me for first place."

His father contemptuously tossed me a card.

"There's a hundred thousand in here. That should be enough to buy your son's worthless life."

I was grief-stricken and demanded justice, but my wife stopped me.

"He's just a child too. Just because your son is dead, does that mean someone else's child should lose their freedom?"

I exhausted myself running around, only managing to get the boy sent to juvenile detention—but that wasn't the outcome I wanted.

In the end, disheartened and broken, I swallowed an entire bottle of sleeping pills at my son's grave.

When I opened my eyes again, I was back on the day I sent my son to swimming lessons.

I immediately turned around and pulled him back home, but this time, a boy still died at the pool.
