Sleeping with Happiness

When a mysterious app called "Sleep with Happiness" appears, those chosen must win seven games of life and death to have any wish granted. Those who fail are either "killed" or reduced to NPCs in the game.

Qiu Yitong's entire family has already been "lost" inside it. When she is chosen, this becomes her only chance to descend into hell and bring her loved ones home.

She soon discovers the truth about the game is far more cruel than she imagined:

In a sinister office, she searches for the rules of death; during a sunny spring outing, she plots revenge for her best friend, who has become an NPC; at a festive college admission banquet, she confronts the darkness of a life stolen from its rightful owner...

With intelligence and resolve, she survives one strange tale after another and gradually closes in on the game's ultimate secret: the "Goddess of Happiness," who delights in human suffering.

At last, Qiu Yitong faces the deity and makes her wish:

"I want everyone who was swallowed up to come back, and I want this game to disappear forever!"

This is the story of a girl who defies the gods to reclaim the little happiness she has left.
