"It's fine because I never had any expectations from the start." A girl abandoned by her family refuses to meet with them when they later seek her help, as she has already married into the royal family as the wife of a prince from a victorious nation.

A story about a girl who was made into a villain finding happiness. The protagonist was framed by a saintess. As a result, she was abandoned by her family. Left alone, she was picked up by a prince of an enemy nation and became his wife. I am also posting this on Alphapolis.
