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 Knights of Favonius Captains.

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 ("What, 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).

Quotes
''"Albedo, eh? Calm, collected, and incredibly talented. He's the type everybody likes, some even more so than others. What, you're into him as well?" Kaeya's voiceline about Albedo.''

''"Relationships are...quite troublesome. Once you establish a relation with someone, you must continue to maintain it; if you lose contact, you must reestablish the relation. This taxing cycle requires a lot of time..." About Albedo – Socializing''

''"The time required to sketch portraits closely correlates with one's mood. I could spend half a day sketching Huffman, while 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." More About Albedo – III''

''"Indeed, I view Klee as my younger sister. Whenever she gets herself into some explosive sort of trouble, I can only console myself with the fact that her current destructiveness is nothing compared to that of Miss Alice." Albedo's voiceline about Klee''

''"Klee. Seems she has failed to elude the Acting Grand Master's investigative skills, despite the pointers I gave her... Haha, I'm kidding, no need to go reporting me or anything." Kaeya's voiceline about Klee''

Fanon
This is Kaeya's voiceline 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, he wrote the Favonius Survival Rulebook for her and always helps her to cover up a big mistake (Their voicelines about her, plus Klee's voicelines), with all of that, there is the headcanon that they might take care of her together.
