My older sister
Prologue


That day happened the first day I entered high school.

To me who looks ordinary

Talking to me normally

An unusual woman


이민하
Hi~!! You're a freshman. I'm Lee Min-ha, a sophomore in high school here.


이민하
Do you like books? I like books.


전정국
Ah... me


이민하
Actually, it's a lie. I don't really like books.


이민하
I just like libraries because of their quiet atmosphere.


전정국
What's going on?


전정국
