Yes, the manhwa follows the novel but there is some light differences, one of them is that the manhwa is moving faster, there is more details on the novel also Hestia is portrayed a bit différently, well the essence is the same but the hardcore otaku side of her is a bit different and the evolution of her relationship with Cael feels more real and is in my opinion better portrayed in the novel.
I like reading the manhwa, I was introduced to this story with it (I won't lie, it's the cover that got me here) but I'm glad I wasn't patient enough for updates and read the novel.
Anyway, whatI wanted to say is that if you were planning to read the novel don't hesitate, it's basicly the same story but the slight differences make it worth it.
Can someone who have read the novel tell me, is the manhwa exactly like novel?
