**Chapter 4: The Dark Groom**

As Shizuo miserably walked away, Osamu Dazai quickly grabbed him, his hands wrapping around Shizuo's waist like a vice. Shizuo's eyes widened in shock as Osamu Dazai squeezed his ass roughly, his fingers digging into Shizuo's skin. "Ah, I really want to fuck you now, but I'll wait till after the wedding," Osamu Dazai whispered, his breath hot against Shizuo's ear. "I'm happy to know my husband has a great ass." With that, Osamu Dazai slapped Shizuo's ass hard, the sound echoing through the room. Shizuo yelped in pain, his face burning with embarrassment and humiliation. "O-Osamu Dazai, p-please," he stuttered, trying to squirm away from Osamu Dazai's grasp. Osamu Dazai chuckled, his eyes gleaming with sadistic pleasure. "Don't be shy, my dear husband," he said, his voice dripping with mockery. "You'll get used to my touch soon enough. And after the wedding, you'll be mine, body and soul." Shizuo felt a wave of despair wash over him, his mind reeling with the implications of Osamu Dazai's words. He knew he was trapped, and that his life was about to become a living nightmare. Osamu Dazai released Shizuo, pushing him away with a cruel smile. "Now, go," he said. "I have wedding plans to make. And you, my dear husband, need to prepare yourself for the life that awaits you." Shizuo stumbled away, his eyes fixed on the floor as he tried to process the horror of his situation. He knew he had to find a way to escape, but for now, he was at Osamu Dazai's mercy. As Shizuo disappeared from view, Osamu Dazai's smile grew wider, his eyes glinting with excitement. He couldn't wait to make Shizuo his, to claim him as his own and break him down into a submissive husband. "I'll make sure everything is perfect for our wedding," Osamu Dazai said to himself, his voice low and menacing. "And when the time comes, Shizuo will be mine, body and soul."
