[This review is spoiler free!] TL;DR: It's a dark shoujo disguised as a josei with a disabled male lead.

I am not disabled, so I cannot speak on behalf of the main character, Ayukawa, or those who have gone through a similar experience. However, I can relate to him in other aspects.

The fear of being a burden to something in a romantic relationship, but still wanting to pursue such a relationship; the choice that follows. I can relate to the desire of wanting to do something but being limited by your body, and your own mental demons. These are all things Perfect World illustrates well.

However, the complexity of Ayukawa doesn't carry to all of the other characters.

Every other character feels rather two dimensional. Kawana, the female lead, is only there to be the female lead. The female supporting character is there to force the female lead to action. The male supporting character us there to force the male lead to action.

Everyone besides Ayukawa feels bland and boring. It feels like the author created a world for Ayukawa and then added characters so his world didn't feel too empty.

There are lots of weaknesses in Perfect World that we could all spend hours picking out: Kawana being a weak-willed girl when it matters, the unnecessary drama, the shoujo-esque storytelling, all the misunderstandings, etc.

As a whole, Perfect World is not a bad read; however, it doesn't feel like a josei either. Instead, it is a blend between josei and shoujo. It doesn't commit itself to the grueling reality of dating someone with a disabilities, and instead leans more into the melodramatic romance. As many other have pointed out, it feels as if Perfect World doesn't exactly know what it is trying to be. Is it a shoujo? or a josei? Is it cutesy? Or is it more realistic? Because the author themselves doesn't know, it can be hard to get truly invested into the writing and characters.

If you intend on reading this, don't go in expecting a full blown josei. Although it touches on darker matters than your typical shoujo, it has plenty of the typical tropes and situations. If you know, you know.
