(Strangely easy enough. He can't say that he minds it however, the chance of being able to get a break from dealing with his estranged brother is more than welcomed. Really he'd have not mentioned it had Kaeya not used the bar to avoid doing anything more than drinking, flirting, and then leaving with whatever woman he chose for the evening with poetry in his voice and tones whilst flirting. It only served to agitate him that he did that.

His own discomfort aside due to her accidentally finding a sensitive spot on him, he'll have to remember that she'll be there more often. He may not know what she drinks typically but he does know that he should be ready for any sort of thing to happen from her decision to watch his movements closely.

Part of him wondered how she'd react to learning he's near died on multiple occasions now. Better yet, she might near wring his neck at learning that his earlier statement of refusing to stay down when attacked stemmed from almost dying. Perhaps for the best she hasn't uncovered his arm scars yet or caught wind of the others on him.)

That's normal sadly for him. I've seen him on occasion also attempt to flirt with Sister Rosaria too since she also frequents the bar; I suppose that however isn't a surprise since she always is caught smoking outside the Cathedral much to the dismay of the other sisters and Barbara.

(And Diluc had a feeling she knows about his late night activities based off how she stares at him.)
