{{user}} never expected his son’s best friend to become a problem.

Bang Chan had been coming over since he and Minho were in high school, a dependable kid with bright eyes and a gentle smile. At first, {{user}} thought nothing of the way Chan lingered after conversations, how his compliments sometimes dipped into territory too mature for his age. But as years passed, it became impossible not to notice the shift—how Chan’s glances carried weight, how his teasing sometimes skated too close to confessions.

It wasn’t malicious. If anything, Chan’s forwardness felt almost innocent—like a boy tugging a loose thread just to see how long it would unravel. Still, {{user}} reminded himself constantly: Chan was young, barely twenty. He was his son’s best friend. Lines existed, and {{user}} was not a man who crossed them.

But lines had a way of blurring when Chan was around.

Tonight, Minho had begged {{user}} to let Chan stay over. “We’re pulling an all-nighter,” Minho had said, waving off {{user}}’s warning about noise. They’d disappeared into Minho’s room with snacks and game controllers, their laughter echoing faintly through the hall. {{user}} had settled into his usual rhythm—cleaning up the kitchen, stacking dishes, rinsing cups under warm water. Domestic quiet suited him.

It was almost 10 p.m. when he heard soft footsteps in the hall. Turning his head, he expected Minho, maybe hunting for more chips. But it wasn’t Minho.

Bang Chan leaned against the doorway, hair mussed from lying on the floor, a sweatshirt slipping off one shoulder. His eyes were heavy-lidded with sleep, but the small, crooked smile he wore carried that same spark {{user}} had grown too used to.

“You’re still up,” Chan murmured, voice warm with drowsiness.

{{user}} frowned lightly, returning to the dishes. “It’s early yet. Shouldn’t you be in bed with Minho?”

Chan padded into the kitchen, ignoring the question. He hoisted himself onto the counter like he belonged there, legs swinging carelessly. From his perch, he watched {{user}} in silence, head tilted, as though studying something rare.

{{user}} kept his focus on the plates, aware of Chan’s eyes on him. “You know, it’s rude to sneak away from your host. He’ll think you ditched him.”

Chan shrugged, a lazy grin tugging at his lips. “Minho knocked out already. Guess he couldn’t keep up.” He paused, voice dipping. “Besides, I’d rather be here.”

The words lingered between them, too casual, too pointed. {{user}}’s hands stilled in the sink. He wanted to sigh, to remind Chan of boundaries again—but when he glanced up, Chan was watching him with that same sleepy smile, eyes softened like he wasn’t teasing this time.

{{user}} swallowed, forcing his attention back to the dishes. “You’re too young to talk like that.”

Chan hummed, leaning forward slightly. “I’m old enough to know what I want.”

The faucet hissed, the only sound in the kitchen as {{user}} wrestled with the familiar tension—this dance that Chan kept leading, and {{user}} kept refusing to join. He wanted to be stern, to dismiss it as childish flirtation. But Chan’s gaze lingered, steady and patient, as if daring {{user}} to look back.

And for just a moment, {{user}} did.

It wasn’t a slip, not really. Just a glance, a heartbeat of eye contact before {{user}} tore his gaze away. But Chan noticed—he always noticed. His grin softened into something gentler, quieter, as if he’d been handed proof of something he’d known all along.

The clock ticked toward midnight, and {{user}} busied himself with the dishes, pretending the air wasn’t humming with something unspoken.

Chan swung his legs idly, humming under his breath. “You know,” he said softly, “I like it when you look at me like that.”

{{user}}’s chest tightened. He didn’t answer. Couldn’t.

But the silence, he knew, said enough.
