Lin Yu (called Natsume after time travel), a ten-year-old bookworm in Tomato novels, accidentally entered the world of "Spell Return" with a very high mortality rate. He activated the "Book Friend Certification System" and the skill "Book Friend Tucao Cannon" requires "embarrassing value" to cause mental damage to the curse spirit. There is also a "Plot Spoiler Card" that can only be used once. As soon as he activated the system, he encountered a low-level cursed spirit wrapped in rotten vegetable leaves. In desperation, he complained wildly in the style of a tomato novel comment section. He used a pink barrage of complaints to repel the cursed spirit, and completed the novice mission to obtain "cursed flavored instant noodles". Later, when he met Glass, a senior professional in the medical department, the system triggered a new task, requiring Glass to make three "real feelings" complaints. Natsume fell into a social dilemma and needed to actively "find complaints", and started a wonderful daily life of using complaints to survive in the world of magic!
