Destined Souls – Underwater Union by ThunderousGremlin

Summary
Sure, the man (well, merman) before him had a fish tail, weird fin-like thingies on his head instead of his old fluffy ears, but it was still Tighnari. His Tighnari.
Even if Cyno had somehow died and reappeared in a strange underwater world. It was still his Nari.“I’m sorry,” the merman said. “I don’t remember.”
But it didn't matter, because Cyno would remember for the both of them.
Yet down there, where the dangers of his job didn't matter anymore, Tighnari was asking him again to marry. Not for love, but to fulfill a nonsensical prophecy to save his people. And not only marry but consummate the marriage too.
Archons, Cyno sure didn't mind changing the order of that.

Summary
“He- You- That’s not-” Kaveh started to fumble. Sure, Alhaitham had been a bit too evil with those comments. But it was ok. It worked for them. It always did. And no matter what Alhaitham could have said, it would never merit being slapped across the face like that.
“We don’t do that here.” Alhaitham summarized diplomatically.
or
Haikaveh bickers as always, but their new boyfriend thinks Haitham is being too mean for his taste and quiets him with a good smack. Needless to say, no one approves of it.

Summary
“Garlic again?” Alhaitham asked displeased while caging Kaveh against the counter; pressed together unnecessarily. Alhaitham didn’t like garlic. Not because of being a vampire, but simply because he hated strong smells, and that open jar of torshi was beyond reasonable.
“Hmm?” The blonde hummed playfully. “Well, I’m scared my vampire roommate will assault me if I lower my guard, so I have to take precautions, don’t I?”
or
Alhaitham's attempts to tell Kaveh he's about to become a werewolf are understood as romantic advances.

Summary
[Seventh part of the Four Leaf Clover Series]
“You need to help Cyno,” Kaveh gasped rushedly. He didn’t know if time was important, but regardless, he wanted to get the matra help as soon as possible.
Alhaitham didn't beat around the bush either.
“Gandharva Ville?”
“Yeah.”
And just like that, Haitham flickered away in a dash of Dendro.

Summary
[Sixth part of the Four Leaf Clover Series]
“Alhaitham, please…” Cyno mumbled low enough so that no one the Akademiya’s welcome ceremony could hear them. “Please not today, Collei has already noticed something’s going on. It’s not the day for this.”
Collei had noticed. Kaveh had noticed. And of course Tighnari had too. The girl of course only knew the age-appropriate explanation that they ‘had a disagreement’, while Tighnari had only been told the partial truth that Alhaitham didn’t trust him to care for a pregnant Cyno, and Kaveh… who knew what explanation Alhaitham had given him.

Summary
Dan Heng exhales a shaking breath and curls against his pillow.
He is keenly aware of Zhongli’s presence on the other side of the door. And though he knows that Zhongli is in another form, he has the brief, hysterical fantasy that Zhongli might rise from the sofa in his human form, come to the door, knock on it, and—
And what?
Dan Heng presses a damp, sweaty palm to his face and groans softly.
When Dan Heng ends up on Teyvat and in heat, Neuvillette and Zhongli take care of him.

Summary
When Kaveh has a run in with a ley line, he suddenly finds that he's changed. Significantly. And exclusively below the belt.
Mortified, and uncertain about how to deal with his new found...equipment, he goes to his safe place for help: Tighnari. The Forest Watcher takes everything in stride and sets his mind to helping Kaveh figure out a solution to his intimate problem. However, things quickly get heated between them, and Kaveh can't help but ask for more.
What started out as just a desperate attempt to get his body back to the way he's always known it to be, somehow ends up with Kaveh spread out across the bedsheets with three of his best friends showing him exactly how to enjoy this change while it lasts.
And enjoy it he does.
---
Whereby Kaveh gets a temporary pussy (because magic), Tighnari eats him out until he cries, and Alhaitham and Cyno end up stumbling in on them, only to immediately join in on the fun. All with consent, care, and communication; because how else would the sumeru boys handle this.
