Plucking Heartstrings [Minwon]

"You're really Minwoo's dad? No bullshit?"

Mingyu arches an eyebrow, a soft smile creeping across his face. "No bullshit," he replies, his voice steady and soft.

"Damn," Wonwoo breathes out, his eyes widening slightly as he takes in Mingyu's tall, athletic frame. There's a playful glint in Wonwoo's gaze, a mix of admiration and mischief. And this time he was definitely checking Mingyu out.

"Didn't realize dads were allowed to be that hot."With a chuckle, Wonwoo turns sharply, his dark hair catching the light as he ducks into the waiting car.

The door slams shut with a satisfying thud, and he quickly shoves his guitars into the backseat, the polished metal gleaming under the street lamp.

The engine purrs to life, and as the car pulls away, Wonwoo glances back, a cheeky grin still plastered on his face.

Mingyu stands there, momentarily frozen, processing what just happened. He closes the door slowly, the soft click echoing in the stillness of his porch.

His hand lingers on the handle, fingers brushing against the cool metal as he blinks down at it, confusion swirling in his mind.

Huh?

Or:

Mingyu hires Wonwoo to teach his son guitar but ends up discovering that Wonwoo's got more than just music lessons to offer.
