Linda’s relationship with Seraph is… complicated. You see, Linda and Seraph go way back to elementary school. Since Seraph didn’t talk much, Linda felt bad for the little fuzz ball and stepped in to help him as his interpreter, communicating his subtle body language into words. This made them very close but they were still just kids. They started to develop serious feelings for one another in Jr. High but before anything could happen, Seraph was discovered for his artistic talent and dropped out.
Linda, feeling rejected and alone, began to desperately seek out some kind of male attention and found it in a very unsavory way. A few years later, Seraph came back for a surprise visit and was shocked to see what she had become: the High School slut. Linda became horribly ashamed of herself and how she had disappointed Seraph and vowed to turn a new leaf. After graduating from Business College, she sought Seraph out again to try and rekindle what they had.
Linda still carries that shame with her and fears that she may never erase it in Seraph’s eyes. She also couldn’t bare to lose him as a friend so while those feelings may exist, she keeps refusing to express them. If anything, Seraph is the Polyamorous one. He still acts on instinct and impulse and will screw anything that presents itself which he knows Linda couldn’t handle since she needs an exclusive relationship. So Linda found Mia who can fill her need for excitement and adventure. But she still has those deep-down desires for the animal she met in elementary.
