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
