The Yandere Villain Is Clingy

[Transmigrate into a book + System (not very prominent) + one-on-one, devoted couple + characters awakening + gradual growth + happy ending]

After working herself to death from overtime, office worker Li Ran is bound to a System from the Plane Maintenance Bureau. She sets off on a carefree path of completing the minimum required tasks and happily lying flat at home. But after reading the tragic ending of a powerful, ill-fated villain in a political intrigue novel, she can’t let it go. Her System talks her into going to that world to save him.

Seeing the huge S+ rating on the task list, Li Ran grits her teeth and asks, “You said this wouldn’t be too difficult. Why is it the hardest level?”

But looking at the rebellious boy, battered and bruised in her arms, Li Ran can only sigh helplessly. And so begins her life of raising a child while earning money.

Watching her little rebel come to her every day with red-rimmed eyes, acting all pitiful as he begs for cuddles, while beneath it all his gaze seethes with obsession and possessiveness, Li Ran asks the System in exasperation: “Has anyone ever actually completed an S+ task?”

Shi Qingli: I thought I was born cursed, that my life, controlled and manipulated by others, had no value in this world.

It wasn’t until I met someone that I learned what it meant to have a home.

P.S. The female lead focuses mostly on her career in the early part of the story, and she’s strong throughout.
