Why Does the White Moonlight System Clearly Say That I Am an NPC?

As an ordinary social worker who just graduated from university, Qiao Ling has understood that he is an NPC since he was a child. In She Runs and He Chases, the heroine is the unfortunate driver who runs away and takes the car. She is also the heroine's little follower in Vibrant Youth Love. Among the professional elite, she is the one whose slovenliness sets off the differences between the male and female protagonists. She understands that the world always needs NPCs, and she is just an ordinary person, but who would have thought that it would be her turn to travel beyond the reach of eight poles? Is she the heroine? It is more realistic to sleep. But there is an extra system in my mind! Qiao Ling immediately became angry! But the system said it was here to support the elderly, so Qiao Ling lay back down again. But time travel means time travel, and she still has a transcarnation, and a college entrance examination directly killed half of her life. I tried my best to finish the second book, but the system said that all five of my roommates were female protagonists. Qiao Ling understood, she was destined to be an NPC. Who says the heroine can't be in the second book! In short, it is enough for her to be her own NPC, earn more money and be less of a social animal, and live with the system in her old age. What? The heroine needs help? A good roommate means stepping up! Here she comes! When it comes to NPC self-cultivation, no one knows it better than me!
