The author did bring her back but ..... in the weird way.
Do you have spoilers? Please tell me what you know.
ME TOO I WANT THE SPOILERS PLEASE
Cmon bbg we're waiting
Hey how? Spoil uuud
Umm no he didn't literally bring her back, there will just be chapters about her past and her side of the story to learn more about the secret behind the MC's birth, and (SPOILER) she'll leave behind something like a video capsule for MC and her father to watch where she'll explain to them things they don't understand and sharing some sweet moments of mc still in her belly when she was pregnant, (it's been so long since i read the novel so i am not 100% sure if there's more or everything i've said is accurate, and there's also a chance the story will be altered or some parts will be skipped in the webtoon)
It always the good mothers who died BRING HER BACKKKK（/TДT)/
