I Was Invisible and Was Regarded as a Ghost by the School Beauty

At the beginning of social life, I actually became the "guardian ghost" of the school beauty? Passing a love letter in the library turned into a mass social death scene. Lu Xiaofan just wanted to disappear where he was! The result came true, he actually knocked himself into the storage room, and accidentally bound a cheating [Prank Survival System] - isn't it scary? Disappear immediately and permanently! In order to survive, he set his sights on Lin Wanwan, the Bingshan school beauty who had just been knocked down by him. I wanted to scare her with a gentle slap, but I used too much force and pushed the goddess to the ground! What's even more outrageous is that instead of calling the police, Wanwan called the air affectionately with tears in her eyes: "Senior? Senior Gu Chen! Is that you?" Lu Xiaofan: "???" Gu Chen? That dead Captain Bai Yueguang? What a huge misunderstanding! In order to survive, Lu Xiaofan was forced to go to work and put on the vest of "Gu Chen's Guardian Spirit". He used lemon-scented paper towels to wrap the corner of the book, used his mind to draw auxiliary lines, and let the eraser "appear" to pass the answers during the exam... He clumsily guarded Wanwan with his system capabilities, but all the credit was attributed to "Senior Gu Chen"! Lu Xiaofan was so sour that he exploded: I did it! It's me! But Wanwan only has her "White Moonlight Guardian Spirit" in her eyes. Lu Xiaofan, who is possessed by the Jealous King, is madly jealous of his dead senior, and at the same time has to complete the system's weird tasks: overturning the little sister's milk tea cup, pouring coffee all over his love rival, making the shampoo weirdly suspended... All kinds of tricks scare the whole school. However, the vest will fall off one day! When Lu Xiaofan exhausted all his energy to save Wanwan, he appeared in embarrassment and fell in front of her... Wearing flying armor, jealous, and practicing supernatural things, this jealous boyfriend is actually me.
