Police officer Liu Qing died.

After death, he discovered he had a new job: full-time childcare.

His younger sister is timid and can only cling to his sleeve. His adopted sister is hot-tempered and rams her head into walls at the slightest disagreement. His daily tasks are to get the little one to sleep, hold the older one back, and keep everyone away from them.

Someone told him his family's deaths had all been arranged, and that he was a pawn in the scheme.

He couldn't protect them while alive. Now that he's dead, he can finally fight with everything he has.

Anyone who touches them dies. He's already died once, so he doesn't care if he dies again.
