Well, the basic idea was really nice. But honestly there were quite a few things bothering me.
Like, yes, Omegas are less likely to get pregnant by betas, but that does not mean it's safe.
Furthermore that they didn't consider normal contraceptives just boggles my mind. In which universe is taking a untested drug the better option over getting a vasectomy or in case of the omega some for of uterus removed. Yes, hormonal treatment like the pill would probably not work on them, but there are other safer options.
And then the whole think about the meds. It made me so mad, like that is not how pharmacy works! Let me tweek the formula, my ass. Even changing one (one!) single bond between atoms can turn a drug from helpful to toxic or useless. Besides that drugs need years of testing. (which is the reason why there still is no vaccine for Covid-19).
I just can't fathom why they went with these choices.
As much as I liked the first few chapters, as soon as the science side got involved, it went downhill for me. And to all those, who desperately want to see babies: not wanting to have children is legit. And a risk for discovery in the world those to life in.
I don't like that Natsuki cheated, but I kind of can understand why he did it. They've been together for a really long time and always close to each other. The novelty wore off, they settled in their love and got used to it. They simply forgot how outstanding and special it was that they found love in each other. Then Natsuki had a really bad day and the thing he wanted to share with his boyfriend he couldn't. He made a mistake, a mistake that made him feel novelty - it was wrong but also exciting. A contrast to their boring life together.
So, I can see why he cheated. But Arata beat him up good, so both did something wrong and it was their mistakes that made them realize what they had in each other and their love gained excitement.
Now, I am still not happy with them. But I am kind of proud that they made up. This story feels really real life-esk, it isn't beautiful or nice, or even perfect. And tbh I don't really like it. But I am glad I've read it. It though me that real love is bigger than than the guys dick you could cheat with.
Okay okay okay, but Ryou-chan's brother!!! now, I want his story
