No, I think she knew Cedric loved her sister in the novel. She mentions how Cedric has a type which is green eyed blondes, and youre right that he gets depressed when she dies too.
The problem Dylan has is that her little sister dies and then Cedric goes off and gets a Happily Ever After with the "true female lead" soon after, while Dylan's family is forever missing a member. If feels like if he was going to end up with someone else anyways why does her precious little sister have to die so young for him? Just to be a plot point for his real love? No way. So she's just protecting her little sister that she loves so much. (From a Big Sister who would do the same lol)

Liie u said..."If feels like if he was going to end up with someone else anyways why does her precious little sister have to die so young for him?"
I mean, he falls for the true fl coz he's depress from losing his wife & baby right? So if she didn't die doesn't that mean there's no problem? It's not like he cheated anyway coz they get together after her sister died..
Idk..sorry if i'm confusing u..i'm just thinking too much lol
This is soo good why didn't I read this sooner?
But i do wonder why did dylan thinks that cedric in the novel didn't love her sister? She made it as if cedric only married her sister coz the grandpa wants it...even if he did, he still loved her sister in the end right? I mean who get depress of losing someone they did not love right?
