Actor Jung Hae-in and his younger brother Jung Hae-jun have once again captured fans’ hearts this time with a glimpse of their brotherly trip to Japan.

On October 23, Jung Hae-jun posted a photo on Instagram with the caption “Brother Run”, showing the siblings enjoying a nighttime jog through Nagoya’s city streets.

In the photo, Jung Hae-in is seen wearing a white sleeveless shirt, his skin glistening with sweat after a night run. Despite the late hour, his fair skin and gentle smile stood out under the city lights.

Beside him, his younger brother Jung Hae-jun sported a black tank top, exuding a sporty and relaxed vibe. Fans couldn’t help but notice how strikingly similar the two looked sharing sharp features and warm smiles that make them look like mirror images.

K-netizens flooded the comments with admiration:

  • They really look like twins!
  • Such wholesome energy I love seeing their bond.
  • Even after a run, Jung Hae-in still looks like he walked out of a drama.

Born in 1988, Jung Hae-in is 37 years old, while his brother Jung Hae-jun, born in 1995, is 30 a seven-year difference that doesn’t seem to affect their closeness.

The brothers’ bond first gained viral attention back in September 2025 when photos of Jung Hae-in departing from Incheon Airport caused a stir online. In one image, a man was seen holding a large umbrella over the actor — leading some netizens to accuse Jung Hae-in of “power tripping” on his manager.

However, the misunderstanding was quickly cleared up when it was revealed that the so-called “manager” was actually his younger brother, Jung Hae-jun.

Soon after, FNC Entertainment confirmed to OSEN:

“Jung Hae-in’s younger brother is officially part of his management team. He assists his brother on-site and is learning through hands-on experience as a member of Team Jung Hae-in.”

The clarification turned what started as controversy into a heartwarming story of family loyalty. Online reactions shifted completely, with comments like:

  • So it was legal labor after all!
  • If it’s your brother, it’s not power abuse!
  • This is the most efficient team operation ever.

Fans admired not only their visual similarity but also their strong sibling bond and professionalism.

Meanwhile, Jung Hae-in is currently filming the upcoming Netflix series Lovestuck, set for release next year.

Their natural charm and genuine closeness have once again proven why Jung Hae-in remains one of Korea’s most beloved actors both on-screen and in real life.
