Hello guys^^

Can u recommend me dramas where ml is exactly like Kang Maru(Innocent man) or Seungyoo (The princess man )...

He used to be nice and caring but something happened to him and changes him into cold and serious person?

Thank u for your recommends^^

The main one I can think of would be Empress Ki (added spoiler tag just in case)

There's also Moon Lovers: Scarlet Heart Ryeo but I'd say this applies more to the second lead. It's still somewhat applicable to the main lead though, to an extent.

Scholar Who Walks the Night maybe? He's rather innocent and kind of weak at first but then he goes through a tragic experience and changes a lot. He becomes more cool/serious and stronger. It already happens at the beginning like in Innocent Man. 

Also kinda Glamorous Temptation. He's not as "cool" as Maroo but still somewhat more serious than his teen self.

  • Nirvana in Fire
  • A Story of a man
  • Temptation of an Angel
  • Also maybe: Love Now, Dream High, 
  • Cross
  • Green Rose
  • Love that makes you cry

Who was good that went bad? If you're talking about the main character I still took him for good
