Anyway, Father is so cuteeee ~ Duke Floyen, I hope you get to actually show your daughter your love. Also, Crown Prince is definitely falling for our Juvel's charms!
The king can use his daughter as a hostage, if the Duke ever considers rebelling. The Duke knows that, which is why he kept a distance from her, that plus his low EQ convinced her that he doesn't care about her at all, ironically, everyone else knows how much he actually cares, except for his own daughter, so his plan was an epic fail.
@anideki wordexcerpt has the license but a subpar translation (you have to start buying chapters by the 11th up to the 37th), though it gives more depth to the chapters of the webtoon. You can also track down the old translation from an aggregate site up to ch 37(bc the other translation you can find in NU starts from ch 38 to ch 50)
i feel bad for the duke, its likely he loved his daughter in the original timeline and went crazy with the suicide, and the dagger was just for self protection.
but man the duke was dumb in the OG timeline imo and did not think in her emotional state and psychology like this one for whatever reason.
Honestly, thinking back to chapter one now after seeing how much he really does care about her is so sad. He cares about her so much, but I don't understand why he makes that so difficult to see. I hope their relationship continues to grow to a point where they can be more open with their feelings.
