Gladiator's Intoxication

“Don’t get yourself into too much trouble while I’m gone,” Kaeya said. The words tasted bitter. “I won’t be here to cover for you.”

“When have I ever,” Diluc said flatly.

Kaeya couldn’t find the right words. “I’ll bring you something when I come back.”

“There’s no need.”

I’ll miss you. But the words wouldn’t come out. I already miss you. I’ve been missing you even though you’re right in front of me.

“Nothing fancy,” Kaeya said, but the smile wouldn’t hold together. “Something small for-” he caught himself on the words ‘my brother.’ “for you.”

“There’s no need,” Diluc repeated, gruff and unfriendly as ever, reaching for another glass.

“Would you at least look at me when you speak with me? If nothing else, I’m a patron.” The words felt like they were being torn out of him, and for a moment, Kaeya see Albedo, arms crossed, with an irritated frown every time he noticed Kaeya thinking about Diluc. Regretting.

Kaeya regretted it immediately, when Diluc did raise his eyes. Flat, hard. They were the same color as they had been growing up, but there was no warmth left in them. “We’ve parted ways, haven’t we, Sir Kaeya?”
