im looking for a manga whe the mc is the only man in the world

[juliomso949]

I dont know it was isekai, but i remember its pretty recent, the mc is treat like a slave and the thematic is something like medieval times

 

[IdanaHamz]

probably not Parallel Paradise

the mc is treat like a slave

 

[gorore]

only thing that would come to mind is mato seihi no slave
looked through the few available manga that have the tags of isekai harem and none met your description so unless you give more details finding it is not quite possible

Mato isn’t even close to that description.
Yukki is the main protagonist, but he’s not the only male. The status quo of men and woman just swapped there.

Closest I can think of is the pornhwa titled

No Man’s Land​

or lewd manga titled

Parallel Paradise​
