A speaker traces the scars on someone's body and, in doing so, imagines the suffering she went through to escape a bleak period of her life. The touch is gentle. The word "caressed" suggests respect rather than curiosity, as if the scars are something to honor, not just look at.
The second stanza turns inward. The further the speaker goes into her story, the darker it gets, yet this doesn't push him away. Instead he falls for her "even more." The darkness becomes a reason for closeness, not distance.
The final two lines state what the poem has been building toward: her soul enchants him more than her body ever could. The scars start as physical marks but lead him to something deeper, her strength and what she has survived. The mood is tender and quiet, a little sorrowful but mostly admiring. It reads like a confession of love that values depth over appearance.
