DUTIES BEFORE DESTINY! Melody is still too obsessed with all things maid to realize she's the heroine with near-invincible powers in an otome game! Instead, she's blissfully living her best life as an all-works maid, unaware she's turning the story on its head. When Melody ends up attending the Spring Ball, all bets are off as new alliances are formed, romances are thwarted, and a mysterious presence crashes the party!
