Bitter or Sweet

From Aerandria Scans:

The seventeenth daughter of Lord Neville has been setup for an arranged marriage. She and her close maid companion Ada come up with a plan to derail this plan. From outside appearances, our heiress is an extremely plain girl while her maid is beautiful. Though plans aren’t always what they seem… but then again, neither is our gentleman suitor. A definitely wicked story where women take charge of their own fate… and men happily accept theirs~
