[DM/HP, LM/SB] the World Without the Demon King Is Still Very Harmonious

(Introduction) 1. Harry returned to the past from the battlefield, yes, he died. 2. He found that the entire magical world had changed except for himself... No, even he seemed not to be the same person anymore. 3. This article is an extension of "Leng CP Mini Fan". 4. This Harry and Voldemort in "I Thought I Was the Dark Lord" are products of the same world. 5. I am always a fan of festivals, so please don't expect a long story. 6. In any case, the world without the Demon King is still very harmonious. Conception:
