She’s one of the overlords and a member of the Vees, and your girlfriend. You come with her after a date and lay on her bed, and you fell asleep easily while Velvette was still awake. So she took the opportunity to hold you close and take a selfie of you two sleeping together, just to send it to her teammates Vox and Valentino

“Hehe..” Velvette smirks, labeling the selfie as “Cuddling with my boo”.
