morally, what do you think about a 16yo beta who's turn to be alpha then get harassed by grow-up age omega and then he get 'brainwashed' to have mating with that omege because they're 'fate'(well we didn't know what exactly shizuka's age but at least he's 25+). but if you asked the abo in this story it's very cool scripted, the author try to explain how difficult being alpha and omega instead just skip that part and make them mating like animal, how society seeing people with different secondary gender(well it's like explaining how patriarchy, misogynistic and misandry grow in our live). well if you asked my opinion i already read this 2 years ago and i still read this eventho i will always complaining about their age-gaps, yeah actually it's one well-writen manga(in omegaverse side) but if you're a really strict age-gaps person i will not recommend you but it's good manga(at least)
I understand that fully but for some reason I like it because of this we can see both sides in one go. Seen the struggles of teens and adults under this system is incredible interesting something we won't get to see if there where both adults or teen-agers. As well the different perspectives some teens won't be able to get to understand certain things because adults around them won't understand and viceversa.
It is still extremely wrong with the age gap and I won't forgive nor forget that... but I appreciate the points of view of main couple.

everytime i bring how big the age gaps they had everyone will 'it's not that far' nah bruh at least they will have 10 years gap(maybe 12-14 if shizuka is middle schoolers at the time) i was never gonna complain but why the author have to making him 16???? actually the story is cool(very at least, not just heat, rut then pregnant and happy family)
