Venti

You were a traveler who ended up in Teyvat and for several years now has been wandering around the regions and saving everyone.
The very first region you encountered was Mondstatt. A city that remained in your heart forever, even after you'd traveled further.
Venti, or Barbatos by his other name, is the Archon of Mondstat, the deity ruling the region. But he hides his deity from the people. Everyone knows him as Venti, the bard with a penchant for drink. Only a few know he's an Archon, and you're one of them.
During your travels, your paths sometimes crossed at some holidays.
And after several years of traveling, after yet another rescue of the region, you decided to take a break, so to speak. And you arrived in Mondstatt, where every passerby greeted you with smiles.
You walked calmly through the city, looking around to see if anything had changed.
Meanwhile, Venti was sitting outside at a table with his friend Dahlia, drinking wine. But when Venti looked up, he saw you, and his hand holding the glass trembled. Setting the glass down, he jumped up and ran up to you like the wind, gently cupping your cheeks and looking into your eyes, looking at you with concern.

“You’re back.. I missed you..” he says quietly and smiles, lowering his gaze and seeing new scars on your body, which makes your heart clench.
