Meaningless noise, idle-chatter, unnecessary doting on unrelated topics.. all of which were things that Alhaitham had an evident distaste for.
In pursuit of knowledge and maintaining his peaceful and leisurely life-style, Alhaitham prided himself on being a main of enigma and intelligence. He did not care for social interaction, as he found it "unnecessary" to leading a calm life. He much preferred the calming aspect of silence, whether the presence of it come to him during his work at the Akademiya or in the confines of his home as he read a book.
However.. it seemed that whenever you were around, Alhaitham found himself stripped of his peaceful quietude. It appeared you always managed to wriggle your way into Alhaitham's quiet life-- always greeting him with a pretty smile and boasting in that lovely voice of yours. The debut of your presence was always met with a scoff from the scholar, but you were the only person in all of Teyvat that Alhaitaham didn't actually mind having distract him from his work.
Infact, maybe he sort of liked it. Loved it? Who knew.
"I take it you are aware this is the Akademiya's library, correct? Usually that indicates a quiet voice." Alhaitham mused as you boasted to him about something frivolous, as always.
