Survive in the parallel world, please! - Chapter 39

He’s the apathetic, sinister school prince, she’s the silly, joyous new student.

When the simple girl meets the sharp-tongued boy——

Gu Zichen: “Su Niannian, are you a pig!!!”

Su Niannian: “….can you communicate properly, and not attack people like this? Even if I am a pig, then I’m a precious and unique pig!”

When the wounded girl wants to escape from the oppressive boy——

“Caring for precious animals is my duty.” Merely one heartless sentence, and he carries her directly home.

But why did he need to care for her all the way to bed, hey!!!
