This sentence is like an unwritten poem. It gently sinks into the heart, as if someone whispers to you in the night—"Every line is your shadow." "Every line is about you" carries a subtle, deep affection, as if the writer, no matter what they write, ultimately cannot escape that person's name. It is both romantic and somewhat lonely, like the tip of the pen relentlessly chasing a memory, each word an echo of longing.
