A phone transmigrates into a book and becomes human. Dazed and confused, it has no idea what to think or do. It even has a name of its own: Qing Ming.
Qing Ming wants to return to reality and go back to being a phone, but the System won't let her. Instead, it makes her deliver candy.
But the more she delivers, the stranger things get.
The gentle and refined eldest senior brother swears he'll always be Qing Ming's big brother and protect her forever.
The aloof and elegant second senior sister resolves to treat Qing Ming like a little sister and dote on her. No one is allowed to hurt her.
The proud, imaginative third senior brother thinks his junior sister is the very best and waves her banner high.
Even the usually aloof Demon Prince wants to protect Qing Ming, and has fallen for her.
Ahem. The three senior siblings frown. Anyone who wants to marry their junior sister will have to get past them first.
But by now, Qing Ming has already taken her delicious candy recipes off to save the world!
