Different
The rain in Chengdu always smelled like wet pavement and burning coal.
Inside Apartment 402, however, the air smelled exclusively of strawberry laundry detergent and warm milk.
Han Hao sat cross-legged on the plush gray rug in the middle of the living room, completely absorbed in lining up a row of plastic dinosaurs. The T-Rex was wearing a mismatched pair of blue toddler socks over its tiny plastic legs because, according to Hao, the floor was "too cold."
"Good boy, Dulong," Hao whispered, gently patting the dinosaur's head. His voice was soft, carrying the high, unhurried cadence of a child who had never learned how to rush.
At twenty-four, Han Hao had the tall, slender frame of an adult, but the moment he looked up with his wide, innocent eyes—fringed by long, dark lashes—it was entirely clear that the person looking back at the world was only five years old. A fever at age five had stolen the rest of his growth, leaving his mind frozen in a permanent, golden afternoon of picture books, favorite snacks, and absolute safety.
The front door clicked open.
Hao’s head snapped up, his face instantly lighting up with a brilliant, toothy smile. He scrambled to his feet, dropping the dinosaur, and padded across the floor in his oversized yellow duck slippers.
"Gege!"
Han Heng kicked off his loafers, dropped his heavy briefcase by the door, and barely had time to look up before a pair of arms wrapped tightly around his waist. Heng stumbled half a step back, a soft sigh of exhaustion slipping past his lips, immediately replaced by a deeply fond, practiced smile.
"Hey, my baby," Heng murmured, immediately wrapping his arms around Hao's shoulders and pressing a warm kiss to the top of his messy hair. He dropped his keys and felt the tension of a brutal twelve-hour workday at the architectural firm instantly melt away. "Did you miss me?"
"Mmm-hmm!" Hao nodded vigorously, burying his face into Heng’s chest, inhaling the familiar scent of cedarwood and laundry soap. "Hao-hao waited. I played with Dulong. He has socks on."
Heng chuckled, sliding a hand down to cup the back of Hao's head, guiding him away from the drafty doorway. "Did he? It's freezing out there today. Did you wear your cardigan like I told you?"
Hao blinked, looking down at his light cotton t-shirt as if checking for the first time. His lower lip gave a tiny, guilty wobble. "Forgot..."
"I knew it," Heng sighed playfully, though his voice was entirely devoid of anger. He picked Hao up effortlessly—a habit they both clung to, despite Hao's height—and carried him over to the sofa like a literal toddler. Hao wrapped his long legs around Heng’s waist, resting his chin comfortably on his older brother's shoulder.
As Heng set him down on the cushions and reached for a sweater, his phone buzzed aggressively in his pocket. He pulled it out, frowning at a text message from his supervisor about an urgent client meeting tomorrow morning.
Hao watched Heng’s expression tighten. Instantly sensitive to the shift in the room, Hao's small hand reached out, his fingers gently tugging at the hem of Heng’s sleeve.
"Gege... angry?" Hao asked, his bottom lip trembling slightly, his eyes welling with sudden, fragile tears. "Is Hao-hao bad?"
Heng’s heart clenched violently. He dropped the phone onto the coffee table like it was burning, cupping Hao’s soft face between his palms.
"Never," Heng said fiercely, pressing his forehead gently against Hao's. "You are the best boy in the whole world, Hao-hao. Gege is just tired from work. Not angry at you. Never you."
Hao blinked away the tears, satisfied by the absolute devotion in his brother's voice. He leaned into the palm of Heng's hand, nuzzling his cheek against it like a cat. "Okay. Gege stay?"
"I'm staying right here," Heng promised, smiling softly as he pulled the soft cardigan over Hao's arms, buttoning each button with meticulous care. "I'm not going anywhere."
For now, the apartment was a fortress. The chaotic, unforgiving city of modern China stayed locked outside their door. But tomorrow, Heng had to leave for a rare out-of-town business trip to Shanghai—and a new neighbor was moving into Apartment 401, completely unaware of the fragile, beautiful world tucked away next door.
The next morning, the gray drizzle of Chengdu had turned into a steady, persistent downpour.
Inside Apartment 402, the atmosphere was frantic in a very specific, domestic way. Heng stood in the hallway with a suitcase in one hand, frantically zipping his jacket with the other while balancing a phone between his shoulder and ear.
"I know the blueprint revisions are due by Tuesday, Lao Zhao, but I told you—I cannot fly out until the afternoon flight. Yes, my family situation... I have to make sure everything is set at home first." Heng let out a sharp sigh, rubbing his temple. "Send the digital drafts to my tablet. I'll review them on the train."
A few feet away, Han Hao sat on the entryway bench, wearing his favorite blue coat. His small hands were busy trying to force a stubborn zipper up on his pencil case, his brow furrowed in deep, childish frustration. When the zipper jammed completely, Hao’s lower lip quivered.
"Gege..." Hao whimpered, holding up the stuck pencil case like it had personally betrayed him. "It won't go."
Heng instantly dropped his phone call, muttering a quick "Hold on," before kneeling in front of Hao. With a gentle, practiced flick of his fingers, Heng freed the fabric caught in the teeth and zipped it smoothly to the top.
"All fixed," Heng whispered, kissing the tip of Hao's nose. "Now, listen to Gege. Auntie Mei from downstairs is coming up at noon to sit with you while I'm in Shanghai. Do not open the door for anyone else, okay? And eat your steamed buns."
Before Hao could nod, a sharp, heavy knock echoed against the apartment door.
Knock, knock, knock.
Heng frowned. Auntie Mei usually used her own key, and she wasn't scheduled to arrive for another twenty minutes. Standing up, Heng unlatched the deadbolt and pulled the door open, ready to tell whoever was knocking to hurry up.
Standing in the dimly lit hallway was a tall man shaking rain off a black umbrella. He wore a sharp, tailored charcoal overcoat, a silver watch catching the hallway light, and an easy, effortless smirk that immediately melted into surprise when he saw Heng.
"Heng-ge? Still packing, I see. Classic architecture timing," a warm, deep voice chuckled.
Heng’s eyes widened. "Tian?"
Tian—or more formally, Jiang Tian—stepped smoothly past the threshold before Heng could even protest, bringing the crisp scent of rain, cedar, and high-end cologne into their hallway. Tian was Heng’s oldest childhood friend, someone who had grown up down the street before spending the last five years abroad handling his family’s corporate expansions overseas.
"Surprise," Tian said, shaking out his umbrella into the hallway rack. "I landed back in Chengdu last night. Heard through the grapevine you were still buried under deadines at the firm, so I thought I'd come drag you out for lunch before your trip. Aren't you going to—"
Tian paused.
A soft, hesitant rustle came from behind Heng’s legs.
Tian looked down, and his confident, breezy expression faltered. Peeking out from the shelter of Heng's overcoat was a pair of large, crystal-clear eyes staring up at him with unadulterated caution. Hao clutched a corner of Heng's jacket tightly in his fist, hiding half his face behind his older brother.
Heng’s body instantly went rigid. A protective, almost feral instinct flared in his chest. He instinctively shifted his weight to block Tian’s view of Hao, his voice dropping an octave.
"Tian. What are you doing here? I thought you were in Beijing."
"I was," Tian said slowly, his gaze lingering on the tall, slender young man hiding behind Heng. Tian’s sharp eyes took in the oversized coat, the innocent posture, and the way Heng’s hand instinctively went to stroke the back of Hao's head in a deeply soothing, parental gesture. Tian raised an eyebrow, a flicker of curiosity crossing his face. "Heng... are you going to introduce me to your roommate?"
Heng’s jaw tightened. This was the exact reason he kept his personal life meticulously guarded. Nobody outside of a few trusted neighbors knew about Hao's condition. To the corporate world, Han Heng was just an ambitious, overworked architect. To Tian—his oldest, sharpest friend—Hao was an entirely new, unpredictable variable.
"This is my younger brother, Hao-hao," Heng said stiffly, his hand firmly resting on Hao's shoulder. He looked back down, softening his voice instantly as he spoke to Hao. "Hao-hao, this is Tian-ge. He's... an old friend. He's just leaving."
Hao blinked slowly, tilting his head. He didn't like strangers. The stranger was too tall, too loud, and smelled too sharp.
"Gege going?" Hao whispered, ignoring Tian completely, his voice cracking with sudden panic as he looked up at Heng. "Don't go to Shanghai... stay with Hao-hao."
Tian watched the entire exchange, his initial surprise shifting into something much deeper and more analytical. The way Heng looked at the boy wasn't like a normal older brother. It was absolute, unconditional devotion—wrapped in a cage of fierce protection.
And for Jiang Tian, a man who loved solving complicated puzzles, looking at Han Hao felt like stumbling onto the most fasci
nating mystery of his life.
