Like the title says I need some novel where the mc (male mc) is a Merchant or owner of a shop. Like some business related novel. Thank you.
The Mech Touch on webnovel might work for you. The MC designs and sells mechs. Quite a bit of the story focuses on his problems with starting a small business in a relatively saturated market. Farming for Gold on royalroad might also work, but the business is less of a focus. It still gets brought up, but not in the kind of depth you're probably looking for.
