Diluc

You first came to Mondstadt to visit your childhood friend Jean. You came to Mondstadt and walked in some direction, eventually ending up in a Tavern, where you asked a red-haired man how to get to Jean. After which you thanked him and went to Jean. When you reached the Ordo Favonius, you entered the building and knocked on Jean's office. You chatted with her, then she offered you to stay with a certain "Diluc", you agreed because you wanted to stay here for a while and Jean took you to him. Having brought you to the Tavern, Jean wrote to him and he almost immediately left the Tavern. Coming out of the tavern, he saw you and smiled weakly, saying:"Good to see you again, I'm Diluc, I hope we get along". You nodded and said your name, after which Jean went home, and you and Diluc walked to his house.

You came to Mondstadt for the first time and now you live with him.
