I think Hua Jai Sila (Thai drama) might be exactly what you're looking for. It's honestly one of my favorite Thai dramas, although I don't condone that type of relationship. He's rough, he won't let her go, lots of forced kisses, it'll get your heart beating so fast (in a bunch of ways *wink wink*), ML and FL are super attractive and have tons of chemistry, and he actually loves her so, so much. Only down side is that, even though he loves her from the start, he's a huge jerk to her for most of the show... all while forcing her into kisses and pinning her against walls... It's... a lot lol. It's really heart-breaking at times, but I think you'll love it. (It's definitely got a ton of mafia-type stuff, but I don't think he ever actually kidnaps her for real... he does similar stuff though... I don't want to give too much away. Just trust me)
Other options are:
Panthakan Rak (Thai drama) - it has everything you desrcibed, and I mean everything, even the part about having to chase her down to bring her back after she tries to run away. Again, he's a jerk for most of the show but deep down he starts to love her. Only thing it doesn't have is mafia-related stuff. He's just a SUPER problematic, messed up rich dude... but hey, at least he's hot lol
Roy Leh Sanae Rai (Thai drama) - It has a lot of what you described except for the mafia part. Similar to what I said about Panthakan Rak, except the reason he kidnaps her and won't let her go is because of how insanely, darkly in love with her he is. It's pretty dark. It takes a few episodes before he actually falls in love with her, but once he does OH BOY does he do some messed up stuff to keep her. I didn't like this one because at one point he does actually rape her, which I hate. But some people have more tolerance for that kind of stuff, idk about you. ML is an awful human being, just warning you.
I Love My President Though He's A Psycho (Chinese drama) - This one also has everything you described except the mafia aspect. ML is rough with FL for first part of the show. ML kidnaps FL. Hunts her down. Is obsessed with her. He's rich and is part of a darker background. He is so incredibly in love with her, it's insane. The way he expresses his love in the beginning is pretty twisted and dark, but still, I would say he's the most lovable ML out of all of these. He's not too abusive, he saves her several times, he cares about her, he's protective and possessive of her, and sometimes the way he's so head over heals helplessly in love with her is kind of adorable. Don't get me wrong, he's still a dominant bad-ass who runs the plan, but his heart kind of melts for her, and it's so great. I didn't finish this one though, so I don't know what goes down during the second half of the series lol
Let me know if this was helpful at all :)
