That scumbag wants to sell her virginity. At least I don't have to worry she will be turned into damaged goods before then.
How to make me despise a protagonist in one line...
It would be fine if he was worried about her mental and physical well being but he quite literally does not spare a single thought about anything like that. Nope, his only concern (as he ponders buying a person) is whether or not she's "damaged goods". To top it off there's a massive dose of hypocrisy as he calls the merchant a "scumbag", apparently lacking even the slightest bit of self awareness. Because it's OK if he does it!
The beginning of this manga was honestly kind of fun because it was so stupid and over-the-top but now that the intro arc is over we seem to be falling squarely into the absolute worst of isekai tropes. And to make it worse the last couple of chapters have lost what originality the early stuff had. It's not stupid fun trash anymore, it's just plain trash.
