Korean netizens can’t get over how much his body has changed… or rather, how much it’s changed back.
NCT’s Jaehyun Shocks With Buff Transformation In The Military
One post on the Korean forum Pann went viral after praising Jaehyun for losing all the bulk he had gained during his enlistment.

In photos from a few months ago [Jaehyun] had gotten a bit tanned and had bulked up with muscle and a little extra weight, but now he’s back to being fair-skinned and lean again, which is so wild to me.
His skin tone is obviously genetic, of course! But it’s not just Jaehyun. Wwell-managed male idols in general seem to eat regularly and work out during their service, so they put on muscle and weight, and then by the time they’re discharged it’s all gone again.

Male idols often bulk up during their service due to regular meals, physical training, and a structured routine. But many start dialing it back months before discharge, knowing they’ll need to be camera-ready almost immediately.

- “Hm?”
- “I really don’t like it when male idols bulk up in the military.”
- “These days they start managing themselves a few months before discharge so they can jump straight back into activities.”
- “They put in the work to manage themselves, that’s why.”
- “Why are people reacting like that. I totally relate to this post.”
