Hiyama Kentarou no Ninshin
Complete | Sakai eri | 2019 released
Very cute manga that considered some serious aspects of pregnancy and how women are disadvantaged by it in society, but didn't delve too deep because it's short. I'm 100% sure the Netflix show is based on this manga and it was a very good show, I recommend it, but unfortunately it erased much of the women and their perspectives and kind of ignored the mangaka's message.
