Loving you is greener than grass

"Of course, Cyno's loved before. He loves many things, the big ones and the little ones.
He loves the forest where Tighnari lives in, he loves the desert in which every time Tighnari steps a foot in, Cyno is forced to carry him back home.
He loves Sumeru, which Tighnari loves as well.
He loves their archon, who gave Tighnari that beautiful, shiny dendro vision that makes him even stronger than he already is.
He loves Tighnari's tail.

And last but definitely not least;
He loves Tighnari.
And Tighnari loves him, too.

But and then?
What do they do after loving each other?"

Or:
Cyno being soft for Tighnari, and Tighnari being reasonable, but also deeply terrified by lighting.
