"Serenity!"
The silver haired princess turned slowly in shame, her moonlit locks tracing the palace floor as she did so.
"You were going to meet the Earth Prince again weren't you!"
A slight blush came to her porcelain cheeks, she had been caught.
"Venus…I…"
"Serenity…" In three strong strides the orange clad soldier walked across to her monarch to be and took her by the shoulders. The young princess flinched, waiting for a berating. Venus sighed. "It's forbidden Princess. You know we're more than happy for you, you know that. We just don't want any more trouble."
She paused, unsure of whether she should continue. She did.

"We don't want to see you get hurt."

The princess's eyes flashed with sadness. She shrugged Venus's hands off her shoulders and turned her back on her guard. It looked as though neither had won this battle, and Venus, having grown weary of the repetitive situation, began to walk away.
"Minako-chan?" The soldier froze in her tracks, in obvious shock.
Then, she removed the mask from her face and after staring at it in her palms for a few moments, she turned to her princess.
"Serenity?"
Her friend's voice was shaky as she asked, "Are we destined to be? Will we be happy Minako-chan?" Seeing Mina's confused face she continued, "You-you're the soldier of love Minako-chan, you know these things!" By now she had ran to her friend's side and gripped her shoulders in anguish.
The change in roles had not escaped Minako's attention. She looked up into Serenity's eyes sadly, her own emotions mirrored in the sky blue orbs before her. They did look remarkably similar, it was true.

Minako wanted to tell her that yes, they were destined to be, and how when they were together their auras shone brighter than the sun. [1]
How their coming together, although forbidden, could potentially bring a unity between two warring planets and they would prosper from thus.
She wished she could tell her best friend that she didn't think they would be happy, because they were already as happy as they could be given the circumstances. That she had never seen her princess quite so happy in all the years she had known her.

But, on her word to Queen Serenity, she was not to utter a single one of these things. The Queen was not as oblivious as her daughter thought she was. She knew what was going on behind her back, and although she wished just as much as Venus did, she could not permit her daughter to see him.
And, as Mars had informed her not a week ago, the love between Serenity and Endymion was powerful and dangerous enough to bring down the whole Alliance, or so she had seen in her fire. This had worried her further, so, she had sent Serenity's four guardians to make sure she did not visit the Terran Prince as often as she liked.
Venus never answered her princess's question. She simply gazed into her eyes and whispered, "I don't think you should be seeing him anymore Princess," and walked away from her, ignoring the gasp she heard.

When she looked back not a moment later, the Princess was already gone.

[1] Something I have read in many fan fictions and on fan sites that Minako / Sailor Venus could tell when two people were destined to be together, because she could see their auras. Some say this is because she was a Venusian, some say because she was the Goddess of Love, some say both. I think it makes sense.
When the two auras matched and/or shone extremely brightly, they were meant to be.
