"You have got to be kidding me-"

Kaeya had to supress his urge to laugh in sheer relief as you dismounted your horse and joined him.

You, his closest friend and best Knight, who was supposed to be recovering after a deep injury, had decided to follow him to an Abyss Order Stronghold.

Was it worry that drove you here? Maybe. Either way, he was relieved to have you by his side during this mission.

And, even if he was ready to scold you for "disobeying clear orders", you knew he wasn't actually mad at you. He cared about you more than he wanted to show.
