What a beautiful story of redemption! With your ending, my little fairy tale becomes truly instructive and endowed with an intense morale. An enemy so able to influence Renhe Ren's life must necessarily be someone close to him, as you say in the commentary to Calluna, and from his death comes the strength to re-emerge from the spiral of misunderstanding and hatred; then there is the theme of altruistic sacrifice, and the theme of never being too late to repair one's mistakes. Truly beautiful teachings!
