Dramas with angst ridden romance that has a forbidden touch to it with the ML falling in love first

Hi everyone! I'm new here and though I've been watching kdramas for almost 4 years , it was only now that it occurred to me to join this forum.
So basically I've seen various dramas ranging from light hearted rom com (Full house, exo next door) to the kind that tear at your heart (goblin)

I recently watched that winter the wind blows after a long hiatus from kdramas since after watching goblin, nothing seemed to come close. And now I find myself in a similar situation again. I tried watching secret love but I just could not enjoy it because I did not understand the office politics which frankly bored me.
So I'm here to ask for dramas similar to that winter the wind blows.
Let me be  a little clearer about the parts of this show I loved:

Both TWTWB and goblin had certain aspects that were similar, aspects that I love.

1)a story that keeps you guessing until the end whether the leads will have a happy ending. I dont mind an overall tragic atmosphere so long as the ending is happy 

2) I love shows where the ML falls in love with the FL before she does. And falls in love hard. But he resists her, resists his feelings because he'll end up hurting her, or because he does not deserve her, or because he knows its not meant to be. Whatever the reason is, he tries to hide his feelings. I need a desperate kind of love because its forbidden (by forbidden I don't mean because of class differences.  It can be due to class differences but there has to be more to it)

3) MLs that are gentle and soft but only to the woman they love. They have hard, edgy personalities in front of the rest of the world but for the FL, they melt and are soft, gentle with them. Treat them with tenderness. I don't like cutesy heros. I need them to have a darkness but I no longer like jerks. In my teenage years  I used to love bad boys but now I find myself gravitating towards the area that falls in the middle of bad boys and sassy characters. I need them to be witty and they can be dark but absolute gentlemen when it comes to the FL. I'm tired of jerks

4) I need a love story that moves me. That makes wait, breathlesly for the moment when the leads finally come together. Again, the parts of TWTWB and goblin that moved me were how the male leads tried so hard to stop themselves from expressing their love but their every act gave them away.

5) the acting. It has to be good.

If someone could help me out, I'd be so grateful! 

Other shows that I've watched to avoid any confusion: 

The heirs

Full house

DOTS

The K2

Goong 

Cheese in the trap

Noble my love

Strong woman do bong soon (I know people loved this and I get why, the chemistry was amazing. Buuuut it was too rom com for me and I need my heroes to be more....dark, complicated)

W two worlds (loved this and it satisfied my angst requirement) 

School 2017

Weight lifting fairy (could not finish this) 

Scarlet heart (this one SHREDDED my heart...I just pretend that the last episode never happened) 

Please don't recommend secret garden, its okay that's love, come and hug me,  encounter 

Haven't made up mind regarding angel's last mission. How is it? I need the acting to be good. I'm a little wary because of the actor who plays the male lead 

Also, is hotel king a clean show? I prefer shows with no explicit content.      


Thanks for reading my rather long list!  

Hotel King It is kind of an clean show There is a bed scene but you can just skip it it is very late into the drama and only shirtless Lee Dong Wook while Lee Da Hae is wearing non exposing night wear you should watch it if you really want this king of storyline lol

While these dramas don't meet the exact requirements, I'd say they hit the major points and were very enjoyable:

Behind Your Smile: dark ML, ML falls first but resists his feelings for her,  good amount of angst and good couple chemistry. 

Devil Beside You: "bad boy" ML but never actually a jerk to the FL, ML falls first, some angst, very good couple chemistry. I actually really appreciated how even though this couple had a lot of problems, they were very good at talking them out (from what I remember). 

Hua Jai Sila: dark ML, ML falls first, a LOT of angst, a lot of push and pull. The problem is he behaves like a jerk but only because he is trying to do exactly criteria #2.  

The Romance Between Tiger and Rose: I know this one isn't really what you are asking for but the couple romance is so amazing! I guess the the ML is kind of dark, he definitely falls first and is total cinnamon roll when it comes to the FL. 

I loved that winter the wind blows and I have been looking for similar dramas too a really good drama  I recommend is The king eternal monarch 

Secret Love Affair 

Chugakusei Nikki 

Autumn Tale 

Something in the Rain 

When I Was the Most Beautiful
