- Era span: 1996 (the heroine is 6 years old) - 2014 (the heroine passes away), covering the urban and rural scene in the late 1990s, the millennium campus, and grassroots changes after 2008, filling the screen with a sense of retro era

- The heroine Lin Youqing: has a gentle and elegant temperament, soft and clean eyebrows, and a bookish air. She looks weak but is tough at heart. She has top-notch grades (the first in the township to be admitted to the key entrance exams and a top student in a normal college). She has excellent writing and beautiful handwriting on the blackboard. She is very patient in teaching. She is the gentlest teacher in the hearts of students. She has a pure and transparent character and a reassuring charm.
- Core tone: Two strong and two-way love + love that cannot be achieved. Both of them are good enough, but due to their class, family background, and fate, from falling in love at a young age to being separated by life and death, the whole process is tragic and reversed, without any perfect turning point. Each chapter is expanded with details to strengthen love and regret.
