Romance dramas about marriages?

I'm looking for dramas like Fated to love You where the drama is about two people in a marriage (its doesn't have to be forced), and along the way there is mutual love? also, you can list dramas that lead up to marriage too :)

thanks

I can only think of "Sunny Happiness" with the premise of people in a marriage for a certain reason until it became love. though I've watched these dramas which was somehow concerned with marriage which are "What is Love" and "In Time With You" and these are really good ones too!! :D

I like those type of series too so I'll offer you a big list. lol
In random order :

*  Wonderfull Life & Dekichatta Kekkon (shotgun marriage)
* Sweet 18, Goong, Delightful Girl, Choon Hyang;  1% of anything (forced marriage)
* 18 vs. 29, Queen of Reversals (already married but need to re-establish their love)
* Full House (all versions), Nagareboshi, Smiling Pasta, Lie to Me & Marriage, Not Dating (lie about wanting to get married/ making a contract-marriage)
* Paradise Farm, Cunning Single Lady, Get Karl!Oh Soo Jung (were once married or about to get married)
* Hana Yori Dango, Boys Over Flowers, It started with a kiss & They kiss again, Playful Kiss, Prince of Lan Ling, Bad Couple, Reply series ; Easy Fortune, Happy Life; Biscuit Teacher and Star Candy, Marrying A Millionaire, Unstoppable Marriage, Hotaru no Hikari, 101st Marriage Proposal (leading to marriage)

I think I'll follow this recommendation post too as I discovered new series to watch. lol
Thanks Koreandramafeels for your rec. I started myself Boss & Me but didn't get to see much of it, but it was interesting. Same with Emergency Couple. I'll watch more of them now..forgot I even started those series. Also, I didn't know about The Eccentric Daughter-in-Law & My Secret Hotel, I'll definitely check them out.

There are a few dramas about marriage that I don't think have been mentioned yet such as 

Valid Love
Words from a Warm Heart
Autumn Shower
Beloved
A Wife's Credentials 
Queen of Housewives
Bitter Sweet Life
Can't Lose.

longer running but well cast Glorious Day, a blind date mishap with one of the Oppas'...followed by female lead's family moving into guest house right next door to the Oppa's. So lots of sweet moments marriage comes much later though, if you don't mind a build up. The pacing is nice
