Well, I need to say that I only watched like 3 episodes. The two main leads are just like I described (an asshole and a poor shy girl) but then there's the ghost girl who is really funny and has a strong personality... idk maybe it gets better, but the whole plot was kinda messed up to me (I don't want to do any spoiler!!). By the way, if you want to see a strong female lead try Healer or It's okay It's love. They're very popular, so maybe you've already seen them, but just in case hehe. Also, one of my fave dramas, Master's sun, started with a douche bag guy and a shy girl but her evolution was truly worth-watching and the actress is my all time favorite :))
PD: Would you recommend me some dramas? I haven't watched a lot and I think we have some preferences in common!!

The MAIN reason why I'd drop a drama is when the male lead treats the female lead like shit, and the poor girl ( who's often shy and with no self esteem) just stands in front of him like she deserves to be treated like that. Ugh, I hate seeing that. When they finally fall in love, it just seems so fake. And I always feel sorry for the girl :(
I dropped many dramas because of this hahaha: playfull kiss, oh my ghost, bof... and many more tbh. When I started with kdramas I felt like this hate-to-love relationship was cute but now I think it's just toxic.
