Merlin, the Flower Magician [Fate Crossover]

"I originally thought this was just a dynasty written about in history books. But when I discovered my name was Merlin, reality hit me hard. I'll meet the legendary King Arthur and his Knights of the Round Table, and witness the love stories and breakups among them. W-wait, my King Arthur can't possibly be a girl!" May Viviane of the Lake give me the courage to crown my one and only rightful king.
