Dramas where the love of a 'good' woman changes a 'bad' man

Hi All,

Does anyone have any recommendations for dramas where the love of a 'good' woman changes a 'bad' man? Any language (e.g. Indian, Korean, Turkish, Japanese, Chinese etc. ) would work. 

Ideally the ML would be someone who is gruff, antisocial, uncaring and/or on the wrong side of law like a thief/gangster/criminal and would hate or be indifferent to the FL in the beginning. I don't want him to be super horrible like a rapist (for e.g. in Sawan Biang) or murderer. But slowly he will fall in love with the FL and change his ways. 

Thank you!

King2Hearts

Falling for Innocence

New Tales of Gisaeng

Boys Over Flowers

I did see Siyah Beyaz Ask and loved it! This is exactly the kind of drama I am looking for....though I think  the ML fell in love with the FL at first sight...

Does Two Weeks have a happy ending?

• Just Between Lovers - He's never really "bad" but he is definitely traumatized, suffering from survivor's guilt, and self-destructive.
• Thirty But Seventeen - ML's true personality is very sweet but he becomes self-isolationist, rude, and socially ... bizarre due to guilt. 
• School 2017 - Gruff, aloof / arrogant, and rebellious.
• The Smile Has Left Your Eyes - Destructive, manipulative, someone who doesn't care about whether he (or others) live or die. He bears some responsibility for the death of another character.
• The Story of Ming Lan - His step mother pretended to dote on him while really working hard to paint him as a scoundrel. After years of being scapegoated and viewed this way (he's not a saint but he's no more of a troublemaker than any of his other family members), he basically decides to lean into that identity. He takes a mistress and makes a lot of poor decisions, but the FL helps him get back on a good path.
• My Secret Romance - A spoiled, lazy, and irresponsible womanizer.
• Something About 1 Percent - Arrogant, rude, rich and an overbearing boss.
• The Great Seducer - Arrogant, rude, rich, manipulative, and self-loathing.
• Arsenal Military Academy - A crass womanizer and heavy drinker.
• 100 Days My Prince - Arrogant and rude.
• Falling for Innocence - Arrogant, destructive, and heartless.
• Marriage Contract - Arrogant, rude, and an overbearing boss.
• Moon Lovers: Scarlet Heart Ryeo - Ruthless, destructive, angry and ostracized.
• Before We Get Married - An aggressive womanizer. He's not a rapist, but you could classify some of his early aggressive actions as sexual assault.
• Madame Antoine - Manipulative / deceptive and does not believe in love.
• Secret - Arrogant, rude and vengeful. 

Okay, so some of these dramas have already been mentioned but I added new ones too (some MLs are not "that bad" but they're arrogant and rude, I hope this counts...):

Love Better Than Immortality - I think this is just what you're looking for. Historical drama but ML is viewed as the villain of that world, he is constantly going against the people who are considered 'good' and even goes against the female lead at the beginning just for power. Him and the FL have a love/hate relationship, begins to change his ways as him and the FL start to fall for each other, turning the tables on the story.

The Romance of Tiger and Rose - ML began by wanting to kill the FL but (Slight spoiler) the female lead knew the plan and stopped him, after that incident the ML began to view the FL very differently and slowly falls for her (While still planning on the sidelines), but he changes his ways as the story goes along, becoming a good person and he actually ends up protecting the place he first wanted to destroy.

Welcome 2 Life - Lawyer who helps criminals take advantage of the law, he gets sucked into a parallel universe where he is a good person, the FL helps him change while solving crimes.
