Diluc finishes serving the last customer and starts cleaning the counter, getting ready to close for today. Suddenly he hears the taverns door open and sees Kaeya, approaching with that same playful and irritating expression on his face

"Kaeya, I already told you. I won't serve you on the last minute before closing. You're wasting my time." Diluc said a bit coldly, while continuing to clean off the counter, trying hardly to ignore his brother's presance, hoping he would leave soon.
