In short, it's comparable to eating chips. It's good when you are eating it, but it isn't filling either.
This is similar to Parallel Paradise. Man wakes up in a world, where he is the only man (hence the title), so if you have read that, you pretty much get the same experience. Since he is one of a kind and has special "pheromones", that makes it so the girls fall in love with him upon touching them, and you can guess the rest of the plot developments from here.
I'm giving it a Mixed Feelings because it's just fine in every department, except in art, which is good. The plot is fine, the "plot" is fine, the characters are fine, the action is fine, the comedy is fine. It doesn't try to do anything extra and it a shame, as in the beginning I had some hopes for some deeper developments regarding the "sole man in the world", but later we were given a rather lame explanation for how they keep up the population and I knew from there, that this is only going to be a surface level story with no deeper mysteries to uncover.
One thing that I want to mention, that there are small unmentioned time skips, where he becomes stronger or learns new magic. I founds this kinda lazy, so if you ask "Since when can he use or do that?", it's always "Learned it between chapters.". The reason I think this is lazy, because he can just pull out anything and totally ruins the flow, like he goes from fighting with a sword to randomly busting out fire magic like it's nothing without any prior mention of him learning fire magic (he was only able to use heal and strengthening magic before).
Giving this series is worth a shot if you just want some popcorn entertainment where you don't have to think, but otherwise I can't really recommend it.
