The General's Little Peasant Wife

She and her boyfriend were both transmigrated into ancient China- he as the heir to a powerful family, and she as a poor orphan. She thought their love could withstand anything, but when he abandoned her for the daughter of another powerful family, she realized she was wrong! Leaving everything behind, she moved to the mountains and swore to only love a man who would be honest with her. She's pretty sure she's found the one, but somehow he seems a bit dishonest . . .
