Nagasarete Airantou, Asu no Yoichi! Recommendations
Mainly harem, romance, and comedy. The 2 guys from each anime both end up in an area that they end up having to adapt to where they were.
Nagasarete Airantou - Ikuto runs away from and is washed up on an island where there are only women there. He meets these different women who are trying to have him fall in love with them.
I know that this summary isn't that good but I really recommend it! :)
