My Sister's Trapped in the Abyss, But I'm Catching Z's

I am the top engineer at the National Deep Sea Technology Center and the only person in the world with deep-sea rescue experience.

When my sister's submarine had an accident and was trapped 10,000 meters deep in the ocean, I hung up her distress call.

Then, without any rush, I went to the police station to turn myself in, claiming I had leaked confidential research information.

A few minutes later, my father called in a rage, "Your sister's life is hanging by a thread, where the hell are you?"
