Through the growth of the male protagonist Lu Chenyi, this book shows the whole process of a boy from "not knowing how to fall in love" to "being able to fall in love":
Stage 1: Like but can't express → Approach awkwardly and often mess up
The second stage: start to learn how to be nice to a person → observe, imitate, practice
The third stage: truly understand what love is → It's not about possessing, it's about making her happy; it's not about being moved by yourself, it's about understanding what she needs.
The fourth stage: running in both directions → both people become better versions of themselves
