Hey I need some help with finding a story I read on Wattpad a while ago but can't remember the name. 
          So the story is either Chinese or Korean and it is about historical times. The FMC is 18, spoiled and engaged with a young man but their engagement breaks and she marries to his brother who is the great general, over 30 years old. He had been living on borders for many years. In the story, female leads brother is also mentioned and he is well-built, a bit rude and he marries to a younger girl (16 I guess). And also if I'm not mistaken on the cover of the story, the female lead has a green outfit. I would be so grateful if you could help me find this storyHey I need some help with finding a story I read on Wattpad a while ago but can't remember the name.
