The cowardly girl Ruan Mianmian caused a scandal that caused a sensation in Deming High School. She carefully prepared a fragrant pink erotic book and planned to give it to the gentle senior classmate in the next class. However, she was highly myopic and overly nervous, and accidentally stuffed the love letter into the desk of Lu Xiao, the school bully who was shocked by the news. Lu Xiao is a top academic who has always been at the forefront of his grade. He has a hot-tempered and cold personality and is rumored to be extremely powerful. All students in the school dare not approach him easily. Ruan Mianmian was horrified after learning about the mistake. She was always on tenterhooks, fearing that Lu Xiao would make things difficult for her. But the situation turned out to be completely different from her expectation. The next day, Lu Xiao changed from his usual casual outfit and put on a full school uniform meticulously. He took the initiative to find Ruan Mianmian with an English vocabulary book and asked her to give him extra lessons based on the content of the love letter. The school bully who once smoked and skipped classes and had an intimidating aura changed completely. He pushed away the cigarettes handed to him by his younger brother and recited ancient poems, just because Ruan Mianmian said that second-hand smoke damages the brain. A timid and cowardly girl unintentionally uses a love letter sent to the wrong person to tame the violent and ferocious big wolf dog school bully step by step into an obedient and motivated loyal dog school bully, unfolding a sweet and contrasting campus two-way secret love story.
