Review: Rare W for the manhwa.

I absolutely love this series and have reread this thing to death but the manhwa is better than the novel.

They actually made the age gap less in the manwha which threw me for a loop. I could be wrong since I read the novel years ago but I believe it was 13 years in the novel but they made it 9 in the manhwa.

In the novel I believe Bianca is 7-8 and Zachary was 20. Crazy fucking age gap. And honestly, if that's too much for you I completely understand and you should probably dip out now lol.

Bianca and Zachary don't have sex until she's 19 and he spent most of the time awary from the manner and had little to no role in "raising" her. So no, there's no weird grooming going in here. The butler raised her.

Bianca was given the ability to go back in time and redo her arranged marriage with Zachary after messing it up the first time and dying a horrid breath. When she goes back she vows to make sure the tragedies of the past don't repeat and make sure everyday says alive. And the core thing she believes to fix this is to mend her marriage with Zachary.

It has a very straight forward plot but it's such an insanely sweet story. Like if you're looking for an OI with 19+ smut with a sexy grey silver fox and an age gap, then this story is exactly your type.

Bianca I find is a really interesting character. Which she's in the body of a 19 year old she retained her memories from her previous life. And while this is normal in all these OI stories, the one thing that stands out in this story is her unprocessed trauma. She comes back with very fresh wounds and emotions. She has a new mission in this life but she lacks in the emotional maturity to handle it at first. She's so traumatized from her last life that she allows a lot of those emotions get in her way. And while it makes sense for her to have those emotions technically speaking none of what happened to her is "real" right. Like what she previously experienced hasn't happened yet. So sometimes her emotional responses are in response to those previous events and it throws off a lot of the other  characters because they can't understand why she's acting the way she is. And what makes it all worse is she refuses / can't tell them.

Bianca and Zachary come to love each other in an incredibly sweet way and are easily one of my favourites couples in OI.

I recommend this series.
