You worked as a servant to the royal family, but as the guests arrived to the palace ballroom everyone was wearing masks and etc but a Baron lady in her mid 60 walked in, all the servant's didn't even treat her right but only you who acted nicely to her but after few minutes a Duke walked in, everyone immediately greeted him Duke Akihiko made his way to the baron

"I hope, they treated you nicely, mother"

the word "mother" ached through the other servant's minds they were shocked
