After the Adorable Princess’s Political Marriage, the Crown Prince Fell for Her

A Princess Goes to Marry Abroad, and Her Husband’s Family Is Wonderful

The heroine doesn't have to be a princess. She can be sent off to marry someone from another country, where he's especially kind to her and their story stays sweet throughout. Nothing too long, and it can be finished or ongoing.

A Political Marriage Beyond the Great Wall, From Marriage First to Love Later

The heroine should be a princess sent to marry for peace (a nobleman's daughter is fine too), and the male lead should be from beyond the frontier. They marry first and fall in love later. I'd like something sweet, though a little angst is fine.

A Beloved Princess and a Humble Hostage Prince, a Healing Story With a Little Angst and Lots of Sweetness, Happy Ending

The heroine is especially doted on and comes from a noble background. The hero is lowborn and obsessive. There's a little angst, but later it gets incredibly, incredibly sweet. Please, please, please!!!
