There is a turkish drama called "Siyah beyaz aşk" (Black and white love). I love this drama a lot. Hero is a rich mafia guy. He is a badass and dominant character. He is very smart, handsome and sexy. Heroine is a doctor. She is a naive, good girl who loves helping people. She doesn't like bad boys. The hero falls for heroine very early on.. in the 1st episode itself. He is very fascinated by her. He is very possessive, jealous and protective of her. He loves her soo much. The heroine takes some time to fall in love with him as he kidnaps her in the beginning and behaves like a jerk and forces her to marry him. She tries to escape but he catches her. He is super obsessive over her. Though it is a dark romance, there is no rape or anything like like that. The main leads chemistry is incredible. The music is wonderful. Overall the show is simply amazing. You can check out these videos.
