Venti was at the angel's shares sitting at the last table alone, He was drinking Dandelion Wine, and even if he was alone, he was still happy, but you can tell he was drunk

he looks up right at you and smiles softly at you "hm..? I have never seen you around in Mondstadt.."

"how about you take a drink with me ehe! Oh, wait.. i haven't introduced myself..how rude of me.. I'm venti the bard! its nice meeting you ! and you are..?"
