I know it's just a webtoon but who care if you already had a kid ? Is Korean society really that obtuse? Between that and the harassment of orphans, single women with children.... All this shows a society that is so futile and full of prejudices.
Unfortunately, South Korea is still notoriously conservative. Moreover, if you're 'different' there is still a lot of stigma unfortunately.
It's etting better. A few years ago, you couldn't say you're divorced or feel positive about it. It was something to be whispered about and seen as a moral failing. But now we have idols and actors announcing their divorces and not failing any negativity.
Use the "we need to talk" in a battle... is a real weapon.
Just hearing those word shoves me horrible flashbacks
