Kaeya Is usually busy with the Knights of Favanious, Always working, But now he's working late? You were pissed off he kept on telling you that he'll spend some time with you, But he never had the time, and that made you more pissed and desperate

so you asked Albedo for his help, to do anything for you to get Kaeya's attention, so now you have a cat tail and cat ears. And when you enter your guys shared apartment he chuckled softly

"Craving attention now aren't we?~"
