Rebeca asked a question

It was a romantic one in a medieval fantasy setting the part i remember is where the main couple got tgt already and a side couple was about to get married. But the husband side of the family was loud ignorant rude and disrespectful, using the husband and discarding him, then coming back crawling like pest to once again take advantage of him. He was recently given a title and thats why he could marry the noble girl he liked. Help me find it pls. I think the main character was the woman in the main couple and the woman in the side couple is her sister i think.
╥﹏╥
I really want to reread it but I lost it among the 100 other I read that are similar

Omg I am crying with her that's so lonely and painful to even think about. I almost slapped the lil guys face when he said he should just stop looking into it like how dare you you are the only one with the brain for it(╯°Д °)╯╧╧
