The idea of writing a campus essay probably started with the Cheese Trap in 2016. It was the first time that I started following a Korean drama from the first episode. I really enjoyed the feeling of being "raised by one hand". Watching this drama go from being unpopular to becoming a hit, I don't know where I got the sense of accomplishment. I am a very lazy person and like to escape. This is the first time I want to write a document for my youth. I want to write this down to reach more people. A story about the other half of a passerby: Chen Shi, a gay friend with no shortcomings: Li Ziheng, a flexible fat man who will be in everyone's memory: Zhai Xiaopang, my good friend: a person without an exact name, they are more or less from my life. I hope everyone who reads this article can find your own shadow in it. This is a new version of childhood sweethearts - winter sweethearts. I wish you a happy reading. Chen is a classmate, and Jia Renlu is a classmate, from school uniforms to wedding dresses, from childish to mature enough to say: I do... This is the main line, it has nothing to do with intrigue, just pure love. Those vague feelings become clearer as they grow up. Okay, the copywriting is useless. The outline was scrapped halfway through writing. I wrote the rough outline based on my feeling. The ability to love people will not disappear. At most, like the name, it comes too late.
