Candy Behr always the brides maid never the bride.

In my game I cheated and aged Candy and Yuki down to toddlers so that they could be childhood friends of my sims. I also "resurrected" grandma Behr to take care of them and made her look more Asian. Judging from their facial features and Yuki's name I always assumed they were mixed. Candy ended up being my sim's high-school girlfriend but they eventually broke up and remained good friends. It's funny, like the op stated, Candy tends to end up as the cool friend but never the love interest of my sims lol
