Chapter 10 My mind is strange enough

Is my sister really my real sister?

One night my parents were not at home, my sister pressed me on the bed

My sister took off my shorts

Since I experienced the comfort, I was not too angry in the end

Later I learned that there are some things that siblings cannot do because they are contrary to ethics.

But what if my sister is not my real sister?

After all, do I have any sisters?

Every day, my sister is not my sister

On the day when I was born, did my sister touch or hug me? On that day, would she be my real biological sister?

Maybe it’s me that my sister changed because of my birth?

If that's the case, where is my biological sister now? Or maybe she has returned to me? My sister may not be my biological sister
