AUTHOR'S NOTE: This fanfiction is heavily influenced by "BLOOD, SWEAT & TEARS" (BTS' Music Video), "DEMIAN" (Hermann Hesse's Classic Novel), "DIABOLIK LOVERS" (Otome Game, Anime, Manga, Drama CD), "DRAMATICAL MURDER" (BL Game, Anime) and "BLOOD BANK" (BL Manhwa, Webtoon). Oh, I took the name "Lee Ha Jin" from "HOUSEHOLD AFFAIRS" (Adult Webtoon), by the way. I hope you can get the ideas of how absurd this is going to be like already. I believe this will be NSFC (Not Safe For Children) very soon, but I will not rate it "M". Don't debate me. Don't trust me. Don't have high expectations. This is nothing but a bundle of mess.
