Help find some stories about the first appearance of "hero and heroine".

Uh, please explain, what does debut mean? Do you want a novel or a paragraph?

Well, it's quite troublesome. You can't copy the whole chapter, just say something and find it yourself.

Introduction to The Bloody Mad Mage Reborn from Another Plane

Rogue Duke 1 Chapter 2 Section 7

A happy ending, chapter one

The first chapter Panlong

…………

Alas, the introduction or the first chapter of almost all books is the protagonist's debut.

But to say something wonderful ... now let me think about it, it's really hard to find. 14 days. Let me see. I'll add it when I find it.
