Kaebedo

Kalbedo is the slash ship between Kaeya and Albedo from the Genshin Impact fandom.

Canon
It's stated that they met and know each other and they are both captains of Knights of Favonius

In Kaeya's voiceline about Albedo, he flatters him by saying that everyone loves him, and some more than others. After that, he clearly say that he is into Albedo by ("Wait, you're into him as well ?").

In Albedo's "More About Albedo – III" voiceline, he talks about Kaeya and the fact that he is teasing him when he draws him ("I might only need three strokes of the pencil to sketch Kaeya — one for the face, one for the eyepatch string... and one for the eyepatch."). The choice to talk about Kaeya here shows that they seem close.

Since Albedo doesn't really enjoy socialize, the fact that he has a relationship with Kaeya shows that he cares about him (Albedo's "About Albedo – Socializing" voiceline).

Fanon
This is Kaeya's voice which motivate this ship and the cute interactions between them.

Plus, since Albedo considers Klee as his younger sister and Kaeya takes care of Klee (Their voicelines about her), there is the headcanon that they might take care of her together.
