Forced Marriage Period Dramas

Hello everyone, 

I am hoping to find a drama were FL is forced to marry either by her parents or the emperor but she never falls in love with her husband. I would also like ones were she decideds to elope with the man she loves. I am just tired of always seeing the FL forgetting her first love after getting married. 

Not sure I know of any dramas that fit exactly, but I can think of a few that are somewhat in the ballpark:

• Moon Lovers: Scarlet Heart Ryeo - At different points in time the ML (4), the ML's brother (8) and the ML's father (the Emperor) all want to marry the FL. She falls for the ML's brother (8) first and then the ML (4), but both of them fail her. The ML's decisions effectively force the FL to marry his brother (13), but she doesn't fall in love with him and doesn't forget the ML (4).
• The Princess Wei Young - The SML stages a coup to become emperor and forces the FL to agree to marry him but the wedding ceremony is not completed. The FL and ML collude to stage a coup of their own on the wedding day.
• Sound of the Desert - The Emperor wants the ML to marry someone other than the FL. To avoid the arranged marriage, the ML is forced to declare that he will not marry anyone until the world is at peace (i.e., never). He later fakes his death and elopes with the FL. One thing you might not like: the SML is essentially the FL's first love, but when she confesses her feelings the SML rejects her (for reasons). The ML doesn't let the SML get a second chance and eventually the FL falls for him. Although she never fully "forgets" the SML, her heart does move on.
• Princess Agents - Hopefully someone else remembers the details better than I do, but iirc the SML falls for the FL, makes huge sacrifices for her and later becomes emperor. The FL is loyal to him (because of the sacrifices) up to a point, but does not fall in love with him. Ultimately she chooses to leave him / go to the ML (the SML's enemy) in order to protect the ML when his life is threatened. In the cliff hanger ending the ML and FL face near-certain death together.
• The King in Love - The FL becomes friends with the titular King and his cousin. Both the King and the cousin fall for the FL. The FL falls for the cousin. Despite the King's clear feelings and the ways that complicates the dynamics between the three of them, the FL and the cousin ultimately elope to be together. 
• The Imperial Doctress - The FL separately becomes friends with the ML (the Emperor in disguise) and the SML. Despite the fact that the ML is married (a political marriage to a nice woman that he does not love), both the ML and the SML fall for the FL. The SML manages to get the FL to agree to marry him too quickly, and later proves to be a pretty horrible husband / person. The ML and FL end up facing a series of hardships together (e.g., becoming prisoners of war) while the SML becomes Emperor. Through their hardships, the ML's feelings for the FL never waver and only grow deeper, while the FL falls for him in turn. But even when the SML is defeated and the ML re-takes the throne, the leads can't act on their feelings because of their marriages and positions. The FL chooses to practice medicine away from the capital, but never forgets the ML. When his son is finally old enough to take the throne, the ML leaves the capital to be with the FL. The obvious caveat being that, in a way, this is exactly the opposite of what you've asked for because the FL does forget her first love. However it's very complicated and done in a way where you 100% will not feel bad about her moving on. He's absolutely awful in the end - he even rapes her.
• Encounter - The FL was more or less forced into an arranged marriage for business / political reasons by her parents. It was not a happy marriage and she got divorced. After she meets and falls for the ML, her feelings never waver even when her ex-husband tries to win her over / her ex-mother-in-law tries to pressure her. Not a period drama though.
