Yes, My Queen (Girl x Girl)
Kathryn, a girl orphaned at 6 after watching her parents be slaughtered by monsters, finally finds herself in a job as a maid for the Queen of the kingdom of Symphonia after being passed around by people for most of her life.
She is shy, reserved, and scared of social interaction, that is until one day she comes face to face with the mysterious queen she works for.
Kathryn soon falls deeply in love with the royal highness, and as sparks fly, an underground war rages beneath their feet, and chaos is soon to come.
Secrets are revealed, dark secrets that nobody ever wanted to know, and Kathryn learns more about herself and her queen than she ever dreamed she would.
It all starts with a simple, "Yes, my Queen."
