I am looking for dramas which portrays similar kind of Romance in 'Siege In fog'. ALSO  I started watching it bcz the male lead looks so much like the second male lead of Bridal mask. If you know the kind of relationship second male lead and female lead had in bridal mask, please mention dramas with similar kind of angst in love dramas.    

Prefers Chinese or Korean dramas and "A BIG NO TO THAI LAKRONS "

The romance of tiger and rose, I´ve fallen for you, Go princess go or you can try some movies from this list: https://mydramalist.com/list/1NkmGV9L but some of them are more agressive than maybe you expect so i would recommend you to watch some which i added 8,5 or more stars. Some of them i didnt watch yet.

@Apollymi

WOW!!! Thanks a lot for your suggestion. I am sure that i will find the kind of stories i am looking for in your list.

And if you know any korean/chinese (prefer korean) dramas where the psycho character has a soft corner for the female lead as in VOICE(2017), or Vincenzo PLEASE SUGGEST.     In both the series, plot is super intriguing .So strong plot with soft corner thing for female lead is what i am looking for.

I didnt watch that series but you can drama Moon lovers: Scarlet heart ryeo - its one of my favourite, Cheese in trap - but i dropped this one so i dont think you will like it maybe its not bad but it depends on my mood, sometimes i need only watch very good comedy to laugh or some very sad drama to cry but of course i still need happy ending.

I went through the Chinese Dramalist you linked here.. But those are not my taste at all.  

Well MOON lovers is my all time favorite too and

 about CHEESE IN THE TRAP , it's my another favorite because I really understood the male lead. Yes he gets back at those who hurt him but he is empathetic and tries to include helpless people in his circle and was really nice towards her once he started loving her. He doesn't talk about the past because if he gets hurt he resolves it in his own way, but the path he takes may not be ideal.  He just makes sure that others get what they deserves for their own wrongful actions. 

And i kind of HATE the SECOND MALE LEAD because he doesn't care about other's emotions or what mental trauma others have to go through because of his hurtful words and he take others for granted.   Cheese in the trap was a whole difference experience for me as far as Korean dramas are concerned.
