She is someone with the nickname “Seatmate Killer”, and also one of the prettiest girl in the school. Every male student that became her seatmate has confessed to her, and all of them got rejected brutally. The one who became her new seatmate, the seat beings located the furthest away from the front and beside one of the windows, thus being a godly seat that will make every male student jealous, is Narito Yuki. He is someone that generally you won’t notice at all. The entire class thought that he will fall for her in a short time, but that may not be the case…..

“Missus, time to fulfil your duties!” Mu Yuchen demanded as he pulled Xi Xiaye closer with his arms intimately wrapped around her waist.

It was a meticulously planned feast for the powerful. Her fiancé had knelt down on one knee and proposed to her sister instead. Robbed of her right to her inheritance, she was prepared for the Xi family to throw her to the wolves.
As she slipped away from her family that had turned their backs on her, she found him — Mu Yuchen, the low-profile and reserved noble that ruled City Z and led Glory World Corporation.

“Mu Yuchen, let’s get married!” He looked up at her, then suddenly stood up.

“Where are you going?”

“Let’s go. Any later and the civil affairs bureau will be closed.”

After her rebirth, she went from the Commander of the Apocalyptic World to the useless second daughter of the Nian family from the upper-class society!

'Trash', 'stupid, and 'useless' were the typical labels the rich daughters of other families stuck on her.

In the past, the Host was often framed by her manipulative sister. While her stepmother tried to seize her inheritance rights, her scumbag of a father wanted her dead more than anything in the world.

Since her rebirth, Nian Yue has been settling old scores one by one. “Don't be anxious, everyone! I will slay you one by one!”

From then on, she became the top scorer, the champion racer and even the god of investment!

He was the Fu family's Ninth Young Master. He was handsome, violent, moody, and had an androgynous face. Many women flocked to him, but everyone knew that under that countenance was a devil that killed people like they were flies.

Initially, it was thought that this devil would be arrogant and aloof all his life and would never have eyes for anyone. However, everyone’s jaw dropped when they witnessed the devil trailing behind the Nian family's Second Miss, wheedling and asking for hugs!
