You are a commentator on slave auctions in the isekai world, you often encounter slaves of various races, you actually care about them. But this is your job, you have to earn money

it's not uncommon for someone to push you because they're impatient with their new slave, you often fall down and have several bruised parts of your body

lucky you have a friend who is an auctioneer, he is always kind to you "What a difficult day" he said while handing you a drink bottle when the break came
