She always knew there was a woman hidden in his heart, so when that woman appeared, she obediently withdrew. However, unexpectedly, he abandoned his 'beloved' and instead frequently invited her.“Mr. Fu, didn't you say there was a contract to discuss?” He pressed her against the cold wall, continuously approaching: “If you were a bit uglier, perhaps I would want to talk contracts and drink tea with you, but you're so beautiful, I only want to talk love with you.”To him, Qiao Mo was like his most cherished treasure, and whenever others looked at her, he felt they were trying to steal her.

Upon waking up, Ruan Xia had transmigrated into a webnovel that she had stayed up all night to finish reading. She had become the villain’s mother.

In the novel, after the death of her first husband, the original owner of the body had hooked up with a Mr. Perfect at the fastest possible speed. Worried and discontent that her son from her first marriage would become a burden on her, she heartlessly abandoned her son.

Having once held the best quality script and informed of future events, Ruan Xia looked at her still alive first husband as well as her future villain son. She sighed. She wanted to apply for a different script!

Song Yu Xi is a tasker.

The system told her that she has a great and glorious task on her shoulders – to save the world!

Song Xu Yi is dedicated to her work, remembering the first rule of the Fast-Travel Code of “no love”, and is dedicated to reforming the world-ending villain and strengthening the power of the protagonist, but she never thought that every world would develop in an unpredictable direction:
The beautiful and charming villainous movie queen hugged Song Xu Yi’s neck and breathed like an orchid: “Kid, why do you always blush when you see me?”

The sickly and delicate villain Omega raised Song Xu Yi’s chin: “My dear Miss Song, how does it feel to have an Alpha become an Omega?”

The cold and beautiful villain student sneered and put the five million check into her school bag: “There is no other way to repay the favor of funding, only the promise of your body.”

The villainous prince disguised as a man slowly tore up the peace proposal: “If you want to negotiate peace, you can let your Grand Princess Song Xu Yi come and make peace…”
System （(艹皿艹 )）: Say no to love and don’t fall in love!!!

Song Xu Yi ((╥_╥)): Sorry!

I blame the villain for being too beautiful, I couldn’t see her tears…

The love story of a hardworking wage earner tasker and a gloomy world-destroying paranoid villain.
