Oh No! How Did My Little Sister Turn Into a Yandere?!

[Single female lead][Slightly yandere younger sister][Mutual salvation][1v1][Brother complex][Slow pace]

Li Yuming's father remarried, bringing him a somewhat aloof and difficult-to-get-along-with younger sister named Gu Xiaomei.

Li Yuming wasn't really good at taking care of people, so he could only figure out his own way of taking care of Gu Xiaomei.

Gradually, the girl's beautiful smile appeared more and more often.

After the class reunion, the drunk boy was taken home by the girl.

The boy was somewhat dazed, and the girl in front of him seemed to be leaning closer.

"Brother...you're being naughty..."

"Don't be a 'snake in the cream' (i.e., steal fish)..."

Li Yuming is having trouble sleeping; he keeps having the same dream lately.

In his dream, he was tied up by a young girl.

The girl in his dream simply stood quietly beside him.

She seemed to have done nothing, yet she also seemed to have done everything…
