Gu Zhen Ren
I smile whenever I remember Ma Hong Yun losing out of pigheadedness his powerful crossdressing harem member that Luck dropped into his lap. It's a sweet situation where they're forced together for mutual benefit, then later he learns about her tragic past and true identity--and he lost everything to do with her because he couldn't stomach it! Thinking now about Fang Zheng, and how his paths might have been different if in the first life he had more fraternal loyalty/trust and less jealousy. Nice when characters' undoings are from their own personality shortcomings.
