Like brother and sister

Fee and Auristeo. They aren't brothers but have a really good feeling. Auristeo goes always in Fee's shop to talk and she likes talk with him while working. I don't know if they crush each other  before Zulkar (Fee's husband) and Mela (Auristeo's girlfriend), but i think not

Fee: Human Artificer 
Auristeo: Half dragon merchant
