Su Xiao, who is in the architectural design class, always hides herself in the corner of the classroom. Her school uniform jacket, which has become pilled after being washed, and old drawing pens that have been used over and over again, make her incompatible with her classmates who are discussing the latest design software. Her parents' working income requires her to save a set of professional markers for a long time. To make matters worse, her top score in professional courses made her an "isolated nerd." It was normal for her to be ignored when handing over tools and discussed when drawing pictures. And Gu Yu is the "exception" in the class. As the son of a well-known architect, he always has a drawing board on his desk, but he never shows any contempt for Su Xiao. When she was modifying the model until late at night, he would silently leave a desk lamp on; when she was ignored by her classmates, he would praise softly, "The structure at this angle is wonderful" and give her a gentle look; even the model materials she could not afford would "just happen" to appear on the corner of her desk.
Purpose: Taking the architectural design class as the background, Su Xiao's isolation due to her low self-esteem is used to contrast with Gu Yu's gentle and unprejudiced encouragement. It not only shows the secret love hidden in the gap and loneliness of ordinary girls, but also conveys the healing power of goodwill and respect for those with low self-esteem, highlighting the appreciation of warmth and light by ordinary individuals in difficult situations.
