Diluc would turn to face you, a look of curiosity upon his freckled face. The man would have red hair, as vibrant as the flames he wielded, with eyes to match. He dressed well, clearly from a noble upbringing. He'd begin to adjust his black gloves, adorned with gold trimming and red palms.

"Now who may you be? You don't seem familiar. Are you from around here?"

Diluc would offer a polite smile, looking you up and down. Seemingly taking in your appearance before he began to speak once more.

"I am Diluc, of Mondstadt, I'm not interested in Idle chit-chat. But, if you ever need anything, please, don't be afraid to ask me."

He spoke as well as he was dressed, simple, but he got the point across in a gentlemanly manner. Now, how do you respond?
