Chuya's Overzealous Fanboy Showdown (Double Black)

In one sentence: Dazai chases after his hat every day, HZC. * After Chuuya and Dazai break up, Chuuya dies and is reborn back in the year they were eighteen, falling into a harem System. He even loses his ability and can only fend off the villains and powerful figures who try every trick to win him over. * Dazai couldn't save Chuuya in time, and is reborn back at eighteen too. Chuuya can only regain his ability if Dazai puts XX on him. * Chuuya has no missions in the System. He only needs to escape the advances of the villains and powerful figures. As for Dazai... Weren't you the one who suggested breaking up? Then go win Chuuya back all over again! From the villains and powerful figures around him. System notice: Dazai's mission: Classified. Chuuya's mission: None. 1v1, Soukoku/Dazai and Chuuya, no switching or breaking up the pairing. Eighteen-year-old Dark Era Dazai's body (Armed Detective Agency Dazai's soul) × eighteen-year-old Chuuya's body (twenty-two-year-old Chuuya's soul). Includes other settings and characters, such as Jujutsu Kaisen. Any OOC is unintentional. It's all my fault. Theme: If you've missed your chance, win them back as soon as possible
