⚠️ age gap

— jk is 23, th is 39
— jk's ex (minseok) is 21. th had him when he was 18
— the age gap is pretty big (it was the only way to make the plot make sense, bear with me), so if you're uncomfortable please scroll away!

“Mr. Kim! Hi!” Jeongguk greets, smiling warmly at the older man once he spots him as he enters the gym.

“Jeongguk-ah, hey,” Taehyung greets back as he gets off the treadmill. He’s heaving a little, hair all damp, and the front of his plain white shirt drenched in sweat.

But it’s when he pulls his collar up to wipe his face with it that Jeongguk feels heat rush to his cheeks.

See, Jeongguk isn’t blind. He’s well aware that Kim Taehyung is probably one of the most attractive men he’s ever laid eyes on.

He’s just  been very good at ignoring it. He was dating the man’s son, after all. And the past 3 months of being at the gym together has conditioned Jeongguk into being totally unaffected to seeing Taehyung in all sorts of forms.

Except right now, as his eyes lay on the sliver of exposed skin of Taehyung’s torso–at the millisecond sight of his happy trail–something inside Jeongguk’s stomach coil.

Mingyu’s words flash in front of his eyes. How was it that he put it? Sex on a stick?

Jeongguk clears his throat and forces himself to look away. “Did Minseok end up coming home last night?”

“He did. At three in the morning…”

Jeongguk winces. “Oh man.”

Minseok was always big on partying. It didn’t bother Jeongguk much at first. He likes going out too like other college students. But Minseok just goes overboard sometimes, and even after Jeongguk has told him so many times to tone it down he never listens.

“God, I know he’s an adult and all but when he’s still living under my roof I can’t help but want to ground him sometimes. He doesn’t even listen to me anymore.”

“That’s understandable. He can be a handful,” Jeongguk says. He’s definitely speaking from experience.

Taehyung sighs. Jeongguk feels bad for him. It must be hard, being a single parent.

“But nevermind that. Sorry. I’m sure you’re not interested in hearing your boyfriend’s dad ramble about how hard it is to parent him.”
