Memories of the Alhambra she likes him, he has very hard time in life and can't see anyone romantically, he is cold (he is cold and pragmatic in general) time passes, she lives her life and he returns (though this drama isn't about romance, main subject is more interesting then romance, really great drama, cinematography and cast, interesting twists and turns)
Girls' Generation 1979 I wont say anything not to give away spoilers, it's 8 episode only and very very good drama, beautiful, I think you will like it. there is what you want and also there is another love story (other FL) Romeo/Juliet kind, really good (every boy in school likes her, perfect girl who falls for towns outcast )
The Innocent Man matches what you want
