My Yandere Little Brother Is Taking Over Everything

A look ahead:

To save myself, I transmigrated into a story about a yandere.

In the original, the male lead locks me in a basement in Chapter One.

I locked him in a wardrobe instead. “Be good. I’ll let you out when I’m in a better mood.”

He laughed behind the wardrobe door, his voice so gentle it dripped with menace. “Big sister, how long do you think you can keep me locked up?”

Later, he crawled out covered in blood and knelt to kiss the top of my foot.

“Big sister, teach me. How can I make you go crazy too, so you’ll only look at me?”

Then one day, I discovered that this yandere had already listened to the recording of my cries for help from my previous life three hundred times.
