Chu Wanchen is the protagonist of the story, a high school freshman with an ordinary family background and mediocre academic grades. Her most distinguishing characteristic is her intermittent, touch-and-go luck, which paradoxically proved crucial when she relied on this ephemeral fortune to squeeze into Qian City's third-ranked Experimental High School during online enrollment. Despite scoring only 525 out of 750 points in the high school entrance examination, her luck allowed her to get accepted when Experimental High School unexpectedly opened admissions in the first batch instead of its usual second batch. Chu Wanchen is a fan of web novels, which helped her quickly accept and adapt to receiving the Almighty Check-In System. She is close to her mother Shao Wenxin, who raised her alongside her maternal grandparents, and she deeply cares for her family. She is thoughtful and practical, deciding to stay in Qian City for high school rather than move to Shanghai, and she aspires to study hard to get into either Tsinghua or Peking University. After receiving the system, she was rewarded with 100 billion yuan and later a luxury villa in Shanghai's Tang Palace Manor.
