Momo slid down the door, her heart pounding as she tried to collect herself. She could still hear Yozora's cheerful whistling echoing in her head. Don't try to avoid me. I'd be very... upset."Who was that?" Hirata's voice came from the kitchen, startling her so badly she almost screamed."H-Hirata!" she stammered, clutching her chest. "Don't sneak up on me like that!"Her little brother popped his head out from the doorway, a mischievous grin plastered across his face. "I wasn't sneaking. You're just jumpy." He squinted at her, his grin widening. "So, who was that guy? Your boyfriend?"Momo turned bright red. "What?! No! He's just a—" She stopped mid-sentence, realizing that technically Yozora was her boyfriend.Hirata's eyes lit up. "Oh my God, it was your boyfriend!""No!" she blurted. "I mean, yes! I mean, it's complicated!"Hirata sauntered over, crossing his arms with a knowing look. "What's complicated about it? He was all smiles, and you looked like you were gonna pass out. Classic couple vibes."Momo buried her face in her hands. "You don't understand. He's... different.""Different how?" Hirata teased. "Is he one of those bad boys you always see in dramas? Does he ride a motorcycle? Oh, wait, let me guess—he's got a tragic past, doesn't he?"Momo peeked at him through her fingers. "Actually, yes. But that's not the point!"Hirata raised an eyebrow. "What's the point, then?""The point," she said, standing up and jabbing a finger at him, "is that you need to stay away from him!"Hirata blinked, then broke into laughter. "What? Why? Is he jealous or something? Does he think I'm competition?" He puffed out his chest dramatically. "Don't worry, sis. I'll let him know you're all his!"Momo grabbed his shoulders, her voice dropping to a whisper. "Hirata, I'm serious. He's... scary."Hirata snorted. "Scary? That guy? He looked like a golden retriever in a blazer.""You don't know him like I do!" she hissed. "He's got this thing about me, and he—"Her voice trailed off as she remembered the knife. The giant cooking knife he had casually pulled out of his schoolbag earlier."And he what?" Hirata pressed, looking amused."And he..." Momo faltered, her hands shaking. "He cooks! Like, really well!"Hirata stared at her. "...What?""Never mind!" she said quickly, letting go of him. "Just promise me you'll stay out of his way, okay? Don't talk to him, don't look at him, and definitely don't let him know you exist!"Hirata rolled his eyes. "You're being so dramatic. He's just a guy, Momo.""Just a guy?!" she repeated, her voice rising. "Hirata, he knows where we live!"Her brother shrugged. "So? Lots of people know where we live."She grabbed him by the shoulders again. "He's been watching our house for years!"Hirata blinked, his expression finally faltering. "...Years?""Yes! And he knows all about you!"Hirata's grin returned, but it was tinged with unease. "Wow. Sounds like he's really invested in you, huh?"Momo groaned, letting go of him and collapsing onto the couch. "I'm doomed. We're both doomed."Hirata plopped down beside her, grinning again. "Hey, at least he's tall and good-looking. You could do worse."She threw a pillow at his face.
