I actually forgot the details of this Manhwa lol but I do understand why you'd think the Ml is an asshole and doesn't seem like he loves mc but I think he really loved her and yearned for her to the point of defying his father(I think that was what happened) but the way he loved or how he showed it was different from what the mc wanted or felt and the miscommunication between the two played a huge part too on why it feels like he didn't love her. I do think as well that ml is an asshat but that's minor details. But I do think had they communicated more ml would've been the love mc was craving and looking for.

ML's mother yearn so bad she passed it down to the men in her family
