I'm honestly pleasantly surprised at the treatment of Akane's eating disorder in this manga. Generally, older manga tend to either glorify disordered eating, or just not treat it as a big deal, but this series actually treats this illness with the respect it deserves.
Akane's health issues aren't downplayed, and they even used the term "eating disorder" when people found out Akane was starving herself. I was definitely not expecting the manga to treat this heavy subject so well, but that's a testament to Natsumi Ando for sure!
