Summary
It was a heatwave, so what better way than to end a long day of work with a boat trip while the sun sets? All three of them never knew what fate was actually awaiting them, and unknowingly walked into an adventure that would change all of their lives. Underneath the full moon in the crater of a volcano, they never knew that they would be bestowed a blessing; or in hindsight, a curse?
March, Stelle and Dan Heng have to find out how to balance their new lives while keeping their secrets without any clue what happened, nor what exactly changed. How difficult can keeping secrets really be when you're one drop of water away from spilling everything? Will the shared secret between them drive them closer or actually apart?
OR
Astral Express trio in a H2O inspired / merpeople AU + more modern setting than the canon universe.

Summary
" “Uhm. I don’t mean to interrupt but…” Sunday spoke up, “…this book reads Ghost Huntin’, A Survivor’s Guide.”
“What?” Dan Heng turned towards him slowly and glanced at the small book. Sunday nudged it closer towards him so he could read it. He had been right. The small book did read exactly that.
“Ghost what now?!” March exclaimed. “Hey, wait— how is this supposed to be the Simulated Universe?! It sounds nothing like what you told me about!”
Stelle shrugged. “It definitely isn’t.” "OR

Summary
"It wasn’t like March was a star in "remembering" trivial things that would happen during her travels. Most of the times, she would just shrug them off and act as if she hadn’t seen anything, practically forgetting the small details.
She would leave it up to Dan Heng to remember the details, while she kept taking pictures of sights that were aesthetically pleasing and worth remembering for decades. But if something were to come back more than 3 times, even she would notice it eventually and know something was off. But she didn’t know *what* it was.
That was, until she got to Amphoreus."

Summary
Robin made her way over to the roof, finally reaching it. It was quiet, just as she hoped. Making her way over to the railing, she leaned against it, looking at the view over Penacony. It was beautiful, more melancholic than she had expected. The silence was as peace to her ears, much better than the bustling venue she was in earlier. With a sigh, she took a sip from her champagne as she gazed up into the starry night sky. Even if the sky was in a dream, it was beautiful.
“Am I interrupting something, Miss Robin?” a shy and soft voice called out, standing in the doorway, Robin turned around to see a familiar person; one that she definitely hadn’t suspected to see today.
“Ah, Firefly. No, go ahead,” Robin said as she turned back to the beautiful view of the city. Firefly joined her, standing next to her in silence for a moment, also having a glass of champagne in her hand. Seeing this, the gears turned in Robin’s head and she figured Firefly probably also escaped from the bustle in the hall.
