When people are defined by society, they gradually lose their innocence and original intentions. It's like a burdened snail, carrying a heavy shell, struggling to crawl through the narrow crevices of life. This state makes one feel oppressed and lost, as if the once pure and transparent self is enveloped in layers of darkness, unable to see the light of day. The lightness and freedom of the past are like feathers drifting in the wind—nostalgic yet unreachable.
