The Supporting Duck Waiting for the Breakup

I have been reincarnated in the body of a supporting character of a Ro-fan novel. Although at first it was a little disappointing I was the irrelevant character that gets divorced four different times and doesn't play a major role in the novel, at the end I thought it wasn't actually that bad.
Because she's still the precious daughter of the “Duck Family”, one of the noble families of our region. She has a ton of people that takes care of her and even helps her to prepare her food and a huge room in a mansion…! Compared to my previous life, this is truly a paradise. To be honest, this might be even better than going through all the difficulties the leads of the story have to endure.

I just had to wait for the 4th and last break that my character experiences by the male protagonist in the novel, but all of a sudden:

“” Wasn't I clear enough? “”
“” …… “”
“” I will never break up our engagement “
What is happening? Is his obsession changing from the female lead to me?!
