The protagonist Su Xiaowu is a "transparent person" in a key high school. Because he is fat, introverted and has average grades, he is often ignored by his classmates and even secretly laughed at by clique (small group). His only safe haven is to hide in his room after class and play the popular mobile game "Fantasy World League", using the ID of "Wuwu" to find a sense of existence in the game.
- For the first time, she had an intersection with Jiang Chenxing, the top figure in the grade and the school's top figure: she helped him pick up the competition notes that had been blown down by the wind, but knocked over his water glass due to nervousness. She was ridiculed by the students around her for "trying to touch porcelain." Jiang Chenxing's silence made her run away in shame.
- In the game, she was matched with "Chenxing" (Jiang Chenxing's ID). The opponent was top-notch but surprisingly patient. He helped her clear the novice copy. Su Xiaowu mistook her for an ordinary high-level player and quietly set her to "special attention".
