Ah yes, a classic plot twist, "the 'commoner maid' was high nobility all along and there fore her marrying the Duke is even more legitimate!", hey as long as they are adorably cute and fluffy together I'm good.

If I wanted depression and drama I would stop escaping reality by reading manga and just live life.
