Read from from chapter 1-3, my opinions is base on these chapter so far.
First off the comment from bobIV123 perk me to read this manga, while drunkguy comments on the other hand where I may agree with his/her un-spoiler section of his/her comment but I don't like how his/her reasoning in his/her comment in the spoiler section that lead to the un-spoiler section comment.
OK, now to me and my opinions. I will judge this manga in three different way. First I would look at the story and/or plot. Next I would judge the manga base on the Author and/or Artist past works history. Usually I don't judge a manga base on this but I will state why later as I type this. And finally I would try and see if it make sense within that story logic.
Another comment I like to stated is that whoever input the genre and/or categories for this manga either has the hard copy and are reading ahead or they just guessing. Either way, for me at least I couldn't find the raw or a translated version of another language of this manga ahead of the already translated chapters (chapter 1-3). So I just like to point that out.
Like I stated, what perk me a little to read this manga was bobIV123 comment, so I read the Description box here. Didn't really help. Then I click on the Author and Artist button to see if they have past work that may help me decide whether to read this or not. When I look up the Artist, his past work were almost entirely "hentai" genre. This give me an early self pre-judgement that this manga may not have a good story. Why you may ask I would think this way? Because almost all the manga I read that that has hentai genre Author and/or Artist move to normal shonen or seinen manga genre with Ecchi/Mature/Adult theme. It always end up borderline or crappy that no different from "hentai" genre itself in those Ecchi scenes. Very few mangaka can do it like normal but most will end up like my comment above if they move from "H" to "normal". With that stated, So far (chapter 1-3) seem normal for a Mature/Adult in term of art and interaction within those chapter. This may change later in the later chapter (I assume) but for now it look normal.
Now on with my comment about the story/plot with a bit of comment back on drunkguy spoiler section reasoning.
Frozen for years, the first thing he does when told the world is falling to ruin due to an ongoing pandemic was to run outside in a blind panic.
(my comment): That a normal reaction which is to panic; the other normal reaction would be denial, cry, get angry, go violent by breaking thing. running way to nowhere but here, hide, or go crazy. Of course they calm down later. A no reaction would be abnormal. The reaction above is the MC is in denial, because when he went to deep sleep the world was fine and he remember it like yesterday but for him it probably is but in reality which he also know is that he slept for 5 year. How you feel if you were told everyone you know and love is gone the next morning. The answer would be some type of reaction that state you care. A no reaction or an indifference reaction answer would be like you don't care.
He is being asked to have sex with more willing beautiful women than there are seconds in a day to help repopulate the Earth. His reaction is pure terror. He isn't gay. His genitals supposedly work. His excuse is that he wants the woman he loves who went missing during the pandemic.
(my comment): I wouldn't call it pure terror but I feel that he (the MC) don't agree with what at hand because he still has the mind set of the past. Come on, it only the 2nd day he woke up. Do you think a normal non-pervert male to jump on the band wagon and go along with the ride.
The author goes out of his way to give every reason why he should have sex ASAP. Nothing is stopping him from having sex and searching at the same time except he claims he won't be in the mood. When he isn't panicking, he mopes, whines and feels sorry for himself.
(my comment): I would agree with the first sentence but the 2nd second sentences to me look like fallacy and need to be correct. To me the 2nd sentence is more of an opinion than information.
To round it up; if you were in the MC position (Assuming you not an overly sexually active person, a sexual predator, or somewhere along these line that get you mark as a pervert or worse). You have to think it through even if you have to agree with the world situation later because that the world reality and situation.
I do however have nagging issue that was mention by bobIV123 comment but not with the same word which is with how almost every female human blush just by the sight of a male human present. I think the mangaka wrote this on purpose because I couldn't think of anything logical and rational (even when I base on other manga with post-apocalyptic or post war situation, expect hentai genre world reasoning). They (the female) should be more worry about what to eat then reproduction because it been stated that most of the world population is in poverty. Even in this situation, a normal reaction from a female would "A Reaction" of some kind but blush would be a "No". If you see a rare animal (aka male human alive) for the 1st time in long time, of course there would be "a reaction" but there will be no blush. That I feel is the mangaka trying to throw normal reaction reality out the window and into borderline-h or H reality world. That blush is like telling the reader that those female is ready to go and to me I say "come on! that the creativity of an hentai genre world. Is that all you got? don't you have a normal reaction without a blush"
Well overall this manga it more hentai like world trying to be normal Seinen world. It trying (base on chapter 1-3) Read it if you want to after reading my and all the other comment here.
Counter comment to drunkguy
just a few counter comment on the new spoiler comment
--Him running out the car and into the urban wasteland was as stupid as a kid sneaking into the zoo exhibit of an angry gorilla.
(my comment): Are you talking about the recent news in Cincinnati Zoo? If it is then my comment about is that is that child did something stupid and part of it blame also go to his parent for not watching the child. Angry Gorilla? No, from my POV of that release video it more like he found a play thing and drag it around. I may not sound very nice but that how I interpret the video. An angry gorilla would show it teeth and attack. Ok enough with that.
"Healthy men need to release their sexual tension whether voluntary or not. With the opportunity and reasons this MC has been given, normal reactions may vary but instant and absolute rejection of sex is not one of them. Most do not prefer their right hand to the company of a beautiful woman but this MC appears to be an exception."
(My comments): this is only comment I have comment about. let me break it now for my opinion.
--Healthy men need to release their sexual tension whether voluntary or not.
(my opinion/comment): Not necessary unless you expect to have sex, this comment is not even a general norm. This comment sound like all men is thinking about sex 24/7 and need to release it somehow. Ehh No.
--With the opportunity and reasons this MC has been given, normal reactions may vary but instant and absolute rejection of sex is not one of them.
(my opinion/comment): I would do the same as the MC but for a different reason. I would refuse at this early stage because it only the 2nd day he woke up, come on. Don't care about why MC refuse but it normal to refuse at this early stage for anyone. But If the MC continue to refuse at later stage given the situation the world is like; then he better have a damn good reason to refuse or I going call him an idiot and |)um3@$$.
---Most do not prefer their right hand to the company of a beautiful woman but this MC appears to be an exception.
(my opinion/comment): I don't understand this sentence expect the last part.
