[Bungo Stray Dogs] I Woke Up and Found I'd Kidnapped Mori Ougai

I, Xilan, owe my life to a doctor from the Port Mafia, who saved me three years ago. Now, three years later, I've come to repay the debt. On my way here, I heard what people have been saying about the Port Mafia lately. In short, a mad boss has thrown the whole organization into chaos and made life miserable for everyone. Worried about the doctor who saved me, I turned to my younger brother, Darjeeling, who'd come with me. Let's kidnap the current boss of the Port Mafia. That night, after we fought our way through a heavily guarded building and returned to our temporary lodgings, my brother dropped the sack from his shoulder. "The Port Mafia boss is pretty handsome, and he's got a nice air about him, too. Never thought he'd be as deranged as you said, big bro." Wait, wasn't the Port Mafia boss an old man? I blankly untied the sack and stared in shock at an old acquaintance, who was still unconscious after my brother had clobbered him. ...Holy crap, Doctor?! A needy, childish wolf pup of a seme who can imitate a dog's bark x Mori Ogai. A sweet short-to-medium-length story. Theme: A story about repaying a debt of gratitude.
