Something like Secret Love Affair, I don't mean noona romance, in fact don't recommend noona romance, I find 99,9% of them disappointing.
What I liked in Secret Love Affair as far as romance goes was the general feel/chemistry between the pair especially in the first half of the series. Another thing I liked about it is that the main characters are normal human, unlike some other romances that come to mind where for example if the male lead suppose to be a jerk then it is his primal characteristic that is underlined in almost every of his action, if girl is bubbly she is always bubbly, if a mc has a phobia then this phobia is pointed out to you in every episode. It's not what, it's how. Right?
Generally I'm looking for romance without over the top elements (be it comedy or melo), with natural progression and without the stereotypical romcom feel. Love triangles are fine as long as it's not the main plot of the story. Happy ending is mandatory. Any country is fine. Preferably something made in 2014 or after (good cinematography gets extra points :p)
Another drama that fits this is One Sunny Day.
Thank you!
