Lu Ziqi, a straight man with an upright attitude, made jokes during the three years of high school. He never failed to look at beauties, fight in groups, and watch pornographic films. However, his grades were role models among his classmates and the treasures of the teachers. Until he met Su Ning, a student who had transferred to another school in the middle, the straight pole suddenly bent and turned into mosquito coils. This forced Lu Ziqi to talk to this good-looking transfer student - what should they do in the future?
Su Ning, a middle-class student according to others, has nothing outstanding except for having a good-looking face. He is ordinary and can be easily ignored. However, he meets the careless, heartless, sunny and kind-hearted Lu Ziqi, who always calls him An Ning every time something happens. He calls him An Ning when he has something good to share. When he confesses his love, he dares not look directly into his eyes but calls him An Ning. Because every time he called him this name, he took it upon himself to taste the endless and graceful affection expressed by Lu Ziqi.
Everyone wants to be a simple person, meet simple love, embark on a journey that is not simple, and live a simple life without fear of the world. You can't do it, but Su Ning and Lu Ziqi did it.
