Next year BG warning
The scheming and cold sister x the arrogant and taciturn brother
Five years age difference
I, An He, have a younger brother named An Yinian
Very naughty, very rebellious and not affectionate to me at all
My mother died early when I was ten years old. When my mother was critically ill, she held my hand and said to me, "Hehe, as a sister, you have to take good care of your brother, do you understand?..."
I nodded and said, okay
(The younger brother's character may change 180 degrees in the later period. Don't read if it's shocking. Quq)
Purpose: My brother is so annoying
