FL is cold and doesn't know what is the love because, she has sad past.
ML feels in love with her at first !!!! he tries to get FL's attention and make her to love him back but, he always get rejected by her
At end,ML's warm and kind-hearted helps FL and she learns about love too
I only know two dramas with this type of story but the ending of both of them are disappointed for me
Swordsman ------> ML gets married to SFL which is still unacceptable for me
Empress Ki -----> ML dies at end
thanks for your help !!!!!
