Chapter 7: The Arrival of a New Obsession

The doorbell rang, shattering the tense silence that had settled over Takashi's apartment. Rina, who had been lounging on the couch, sipping a cup of coffee, set it down and rose to answer the door. Takashi, still reeling from the morning's events, remained seated on the bed, his eyes fixed on the floor. Rina opened the door to reveal a petite girl with short, spiky black hair and piercing brown eyes. She looked no more than 16 years old, and her small frame and delicate features made her appear even younger. She was dressed in a tight-fitting black dress that seemed to be several sizes too small for her, and her cheeks were flushed with a mixture of excitement and nervousness. "Ah, welcome, Mitsuki-chan," Rina said, her voice dripping with sweetness. "I'm so glad you could make it." Mitsuki's eyes darted past Rina, locking onto Takashi, who was still seated on the bed. Her face lit up with a bright smile, and she bounced into the apartment, her eyes fixed on Takashi with an unnerving intensity. Takashi felt a shiver run down his spine as Mitsuki approached him, her movements quick and jerky. She stopped in front of him, her eyes scanning his face with an unblinking gaze. "Hi, I'm Mitsuki," she said, her voice high-pitched and breathy. "I've heard so much about you, Takashi-kun." Rina chuckled, settling onto the couch beside Mitsuki. "I'm sure you have, Mitsuki-chan. Takashi-kun is quite the popular fellow, isn't he?" Mitsuki's eyes never left Takashi's face, her gaze burning with an inner fire. "Oh, yeah. I've heard he's really good at... certain things." Takashi's face went hot with embarrassment, and he looked away, trying to avoid Mitsuki's intense gaze. But she was relentless, her eyes following him as he tried to hide. Rina laughed, reaching out to pat Mitsuki's shoulder. "I'm sure Takashi-kun would be happy to show you his skills, Mitsuki-chan. But first, let's get to know each other a bit better, don't you think?" Mitsuki nodded, her eyes still fixed on Takashi. "Yeah, that sounds like fun." As Rina began to chat with Mitsuki, Takashi couldn't shake the feeling that he was in trouble. Mitsuki seemed even more perverted than Rina, and her intensity was unnerving. He wondered how he was going to survive this new addition to the harem, and whether he would be able to escape the web of obsessions that seemed to be closing in around him.
