I created three teenagers and had them living together in Willow Creek -- Matthew, his destined wife Blaire, and their mutual friend Angela, who is like a sister to both. Or at least, that was the plan. Instead, Blaire developed a crush on Angela, they autonomously flirted, and became an item -- at least until prom, when Blaire evidently flirted with someone else, leading to she and Angela fighting so much they became enemies and I had to change the house plans a bit so Blaire and Angela were no longer sharing a bedroom. I've never had a full relationship develop, bloom, and then combust like that on its own!
