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.
