For the rarepair meme, I'm not entirely sure what actually qualifies in Genshin XD but Lyney/Nilou? I do kind of like the idea of two of our performers together....
I can see a very clear rivals to lovers thing, at least rivals from where Lyney's standing of course. Kinda like this (excuse the Lynette POV, that's how the scene showed up in my mind and she is very fun to write):
*
The Traveler couldn't stay for tea but she left Lynette a box of beautiful little honey cakes brought fresh from Sumeru. She was supposed to share with her siblings and she would do that, there were far too many for her alone anyway, but that didn't mean she couldn't hide away in her room with a pot of tea and enjoy some peace and quiet. And honey cakes, of course.
It was barely time enough for her to bite into one of the cakes before Lyney invaded her peaceful tea-time, giving his usual knock and entering before she even answered.
There was urgency in his voice as he said, “Dear sister I found out the reason behind the last few nights' shows lull in ticket sales.”
Even if Lynette was inclined to ask, she knew better than to do that. When Lyney has a plan you can see it in the very way he moves, and from the way he sauntered to the table and pulled the chair closest to her, this was a fun one. At least fun for him.
“We,” he said, eyes twinkling, “have a rival!”
Now, if she wanted him to say his piece and go away, she was forced to show attention. So she deposited her teacup on its saucer and tilted her head toward him, waiting.
“A Sumerian dancer, come here to perform for a half-season, and a famous one at that. It's all over the Steambird! We can't just lose tickets for all that time!”
Lynette blinked slowly at him, then refilled her teacup. “And your plan?”
“Who said I have a plan?”
She smiled and waited.
“I've been to her act. She's very good. Disciplined. Working elemental magic while dancing must be very tiring but the results are,” a brief, breathless pause, “stunning.” There was a little too much shine in his eyes as he said that. “As is her-- I mean, her movements. The way she dances, it's like the rest of the world stops existing, I can't help but wonder…”
As Lyney's eyes took a dreamy, faraway look, she knew it. It was a bad plan. The worst kind. She felt her right ear twitch, an old tell she usually keeps under control. That is how worried he made her.
Lyney noticed as well, he snapped back to attention, said, “That's when I knew I had to do something.”
“That plan. You shouldn't.”
“Beloved sister, I said nothing--”
The teacup clicked in its place on the saucer. “You want to distract her from work, maybe make her go away earlier. Don't. It'll backfire, you're too smitten. Remember what Father said about you and love schemes.”
The mention of Father had him straightening up, as usual, lifting his chin as if trying to stand a little taller, fill bigger shoes. Then he said, “Well, we'll see about that, won't we?”
And that was in the wrong tone. Not so much defiant as… She studied his face for a moment. There was that smile, a bit too much eagerness there. This could only mean the plan was already in motion. “Don't say…”
The smile bloossomed as if every single drop of confidence he had nurtured it. “I'll be taking her to Lady Furina's new play tomorrow!”
Nothing she could possibly say would work at this point, so she saved herself the energy and took a sip of her tea. Afterward, she said, “Then good luck on your date with the beautiful dancer.”
Lyney paled, the smile dropped just enough that she knew he had only now caught up with what he had done. “Thank you,” he said, quite like an automaton. Then he walked away, a little spaced out.
Lynette hoped her brother would pull himself together enough to be his usual self on the date. That should be enough to charm anyone. And if that didn't work, well then she'd have to do something, wouldn't she? Maybe the Traveler would even help.
