ok so this setting is historical korean-ish. Uke is kinda a doctor studying medicine with his teacher and bunch of other disciples deep in the mountain.
One day, seme showed up all wounded, nearly dead. Uke begged everyone to save his life. They hesitantly did. Nothing extraordinary happened after that, but the entire clan got massacred by seme. I'd say it's mainly seme's jerkness's fault plus some human jerk in the clan's fault..
