Antagonist is the Protagonist (antihero)

Maybe "Word of Honor" - one of the main leads (wen kexing) starts out being kinda evil. 

 Ichika Kaneki:

Any drama where the main character mc, ML or FL any, start out as antagonist end up as protagonist . or like theyre protagonist but evil enough to be considered the antagonist

• The Smile Has Left Your Eyes - ML
• My Mister - FL
• Doom at Your Service - ML
• Fall In Love - ML
• Hotel del Luna - FL
• Hello Monster - ML
• Moon Lovers: Scarlet Heart Ryeo - ML
• The Romance of Tiger and Rose - ML
• Secret - ML
• A Korean Odyssey - ML
• Empress Ki - ML
• The King's Woman - ML
• That Winter, The Wind Blows - ML
• Misty - Both in different ways

 Czakhareina:

Maybe:

• Cruel City
• Bridal Mask
• Mr.Hiragii's Homeroom
• Todome No Kiss
• Punch
• Bad Guys

Yes to every single one + the first three are what I consider must watches of their genre~

of course Light Yagami of Death Note, the famous villain protagonist

yup, the majority would agree with you lol. at least it was decent as a fantasy manga adaptation, i wouldn't say the same for some others....

Untamed - Wei Wuxian
April Star - Ye Fan Xing
A Tale of Thousand Stars - Tian Sopasitsakun
Ice Fantasy - Ying Kong Shi
Introverted Boss - Eun Hwan Ki
Moon Lovers - Wang So [4th Prince]
non-asian drama Once Upon a Time - Evil Queen / Regina Mills

*but some of these dramas are like they werent evil, only people thought that they are

haven't seen anyone mention it yet but Beyond Evil and Mouse are both good watches <333
