On How to Kill Popular Characters from Both Sides

I'm tired and don't want to write an introduction. The content of this article is as indicated in the title. ———— The author who has already laid down remains. This is the upper part, the lower part is newly opened, titled "On How the Villain Can Win" Tender and gentle on the outside, hard-hearted on the inside. Heartless, meaningless, dark and cruel. Take the initiative to stir up trouble and be more calculating. How can falling in love be as good as using your brain to build a career? Mine warning: 1. An atypical heroine with ordinary looks, no supernatural powers or superpowers, 2. The heroine has no moral concepts of truth, goodness and beauty. The main villains, Zan and Black Mud, will not have a normal happy ending. 3. The emotional line is unreliable. I repeat, the big villains, Chips and Black Mud, will not have normal relationship endings. 4. This is self-produced food, and I just want to write a story with a true end. The final interpretation rights of the above definitions belong to the author. 5. The writing is poor and it's just for love, so please bear with me. You can leave at any time if you don't like it, but please don't attack the author. 6. This article uses Detective Conan, Bungou Stray Dogs, and Tutor as the main background, interspersed with personally oriented animation works such as "The Lonely Planet in Tsubaki" (comic), "Brothers' War", and "NANA". Intention: life without love
