After Transmigrating Into a Book, I Healed the World-Destroying Witch Into a Yandere

[Western Fantasy] + [Slow-Paced] + [Single Heroine] + [Developing Yandere] + [Golden Finger]

He transmigrates into the body of a useless servant with no System and no talent, then gets sent to serve a witch who could lose control and kill someone at any moment.

It’s fine. He just wants to do his job, change her fate, and stop her from becoming the boss defeated by the protagonist’s party in the original story.

He cooks, cleans, keeps watch over her, and talks with her.

She finishes her meals, puts down her blankets, and starts talking to him.

Everything is going in the right direction.

Until one day, someone tries to hurt him.

For the first time, her magic erupts to “protect” rather than “destroy.”

She steps in front of him, her white hair whipping in the storm of magic. When she looks back at him, his reflection fills her red eyes.

“You dare lay a hand on him.”

Her voice is soft.

“You’re my servant. You belong to me alone. No one is allowed to touch you.”

Lin Feng suddenly realizes he may have healed her a little too well.
