I do agree that it’s strange how the reader doesn’t know about the father’s affection for his daughter. However if you were the average reader of the novel from the story, where you didn’t know about the father’s affection for her, a knife given for suicide wouldn’t be that suspicious. Like what else would you think that this honorable grand duke, who dislikes his daughter, would give the knife for? But I do agree that there are plot holes, especially with how the story suddenly ended. It seems pretty obvious that there was a misunderstanding and the author really could’ve done a plot twist or something which would make her story much more entertaining. What author would leave a plot device like that to rot and just end it

SPOILER
Actually, the first thing I will say is not a spoiler since it was said before in the webtoon : The dad said to Max that a weapon is not to kill but to protect someone or to defend yourself. In a way, he gave his precious dague to his daughter so that she can protect herself since he won't be there. Just by hearing this, I already thought that this was his intentions.
Secondly, and this is a spoil, the crown prince which is Max, was sent by the Duke to protect her in exchange for the duke to stop being neutral and supporting him as the next ruler.
But there is something I don't really understand from your questions, what rumors are you talking about? We have the time to discover if it was right or wrong, there is no need to be impatient. ╮( ̄▽ ̄)╭

I disagree. 3rd Person Narratives may not be biased, but they're not omniscient. This kind of POV can exclude and include certain narrative details to fit the structure of the story better. Think of it this way; third person is when the words 'he, she or they' are used, and omniscient is when an unknown narrator relays the story with multiple POVS being used, and no narrative bias at all.

Since the 3rd Person POV is biased, adding all the narrative clues and examples we've got so far, it's only logical to assume that the father gave her the knife so that she would kill herself. Not to mention, if the story ended after that then there were no other clues to disprove the Duke's neglect of his daughter aside form a single 'Endure it'. Most readers do consume content mindlessly, and the ones that don't probably take some time to analyse. That being said, since MC has isekaied, I'm sure her survival is more important to her then the 'will he/won't he' question of whether her father loved her or not.

What I meant to say here was, since 3rd Person POV are baised, the readers couldn't have known that the Duke loved her. 3rd Person POV do focus on a single character, only they narrate the story from a he/she/they POV, whereas Multiple POVs focus on multiple characters, and Omniscient POVs focus on the thoughts, feelings and stories of each and every character as though the author is narrating the story.
There are major plot holes in the original storyline. If it’s said that her father loves her so much, then why wouldn’t a reader know that if the story is told from 3rd person point of view?
