I Choose to Be an NPC in the 101st

A veteran heroine who has traveled through a hundred books decides, in book 101, to abandon all main quests and become an ordinary bookstore owner. She just wants to drink tea, sell books, and watch others' stories. But the heroes, witches, princes, elves, and dwarves she rejected keep showing up—not to recruit her, but drawn to her peaceful daily life. One by one, they leave their own scripts and gather around her bookstore. When a cross-world rift threatens everyone's existence, she has no choice but to close the door. Afterward, she returns to her bookstore, still brewing tea, soaking up the sun, and watching former protagonists become neighbors. Core: choosing to stop, to be no one's hero, yet unexpectedly becoming the center where everyone converges.
