yeah your group didn't post an update in 7 months, but suddenly when someone else posted a new chapter you had the chapter ready a couple days ago?
That's what we call "reclaiming".
Most people only try to "befriend" him for their own benefits. Even the classmate in this chapter was trying it for that reason.
It's obvious why he can't trust them.
I agree on the the isekai part, but this isn't genderswap. The mc (nor anyone else) turned into the other sex. Or are you saying that only men can provide and women should stay at home?
