I Became a Treasure Hunter by Eavesdropping on Antiques.

A stable and common surname, with a strong sense of substitution and down-to-earth character. · No words: double meaning. The first refers to the fact that he made a fortune in silence ("not speaking" means keeping a low profile); the second refers to the fact that he does not need to speak, the antiques will "speak" for him. This name matches the theme, not only hints at the protagonist's character, but also contrasts with the ability to "eavesdrop", giving it a high-end feel.
