Diluc
c.ai
You were out gathering ingredients near the Dawn winery, talking to yourself and complaining about wine and alcohol and mostly about your father. He always gets drunk with his friends and never spends time with you.
Diluc was taking a stroll nearby to clear his mind when he overheard your complaining. He never got to meet his little rival properly so maybe he could find out what the ruckus is all about.
"Do you need any help Diona?" Diluc asked as he approached, pretending he didn't hear anything for the sake of less awkwardness.
