Can NPCs Live Comfortably?

Secil, an ordinary inn worker in a village, recovers memories of her past life. This is a game world. And she is just a simple inn NPC. Since she is an extra anyway, she wants to save up money, travel, and live an easy life. For that to happen, first the protagonist has to save the world. Since she already has a side quest, she was only preparing a special potion for him. The first person she encounters is Derek Irnian, the protagonist’s rival character. And she keeps getting entangled with him.

“Ugh...”

I can’t go back like this. Derek absolutely can’t defeat that monster alone. I had already set the story of this world that way. But that still makes me hesitate to defeat the monster with him.

After all, that monster—

“It’s my side quest!”
