This is just my opinion, you may very well disagree with this.
I don't really like the premise, or I might simply look for the wrong romance manga (than what I prefer). Many men might like this, I mean, who doesn't like all you can f*ck buffet with no commitments. But to me, I'm just confused.
The MC, who doesn't seem to have any experience, married a girl, who is a slut and most likely already has a baby in her belly (assuming that she holds up her "no rubber" principle) then didn't even want to touch her while she lets herself touched by her school friends (or maybe by some old men too, idk, it was not described) because she's not legal. The heck is this? Ain't no way I had this kind of fantasy.
Or maybe I'm simply outdated and I can't adapt to how the world works nowadays. Or maybe I'm just a dull person who can't handle high schoolers f*cking each other, sluts who separate s*x and romance, and the principle of f*cking around as much as you can before having a real romance and settling down. Or I'm just a bitter person who can't stand a fictional story.
I would be okay if this is an adult story, I mean, some smuts have similar backgrounds. I would be okay if at least MC was not some virgin (literally and figuratively). Why does everyone seem to like a romance of an innocent good boy and a slut who has f*cked 100 guys then thought that it might be the time that she finds a very good innocent saintly boy who will take care of her (and maybe her baby if it applies) nicely without judging her past and is different than those flimsy guys she had f*cked who can't even take commitments at all but she f*cked them anyway because s*x is fun?
Hell yeah, maybe I'm not cut to live in this world and this planet.
