they are meant to represent the two polar opposites within my mind. i have BPD, so I've always struggled with extreme mood shifts, and these two represent the two major emotions i commonly feel. they are identical in every aspect, the only physical difference being the color that represents them. they are both deeply emotional beings, and they find comfort in loving eachother in ways they wont receive with other people. yes they are in love... OOOO selfcest so scary oo.. I am very emotionally attached to them!!!
