In a world of more than eight billion people, even though every individual is a unique being with their own distinct characteristics, nature sometimes seems to delight in creating astonishing coincidences. While physical similarities between ordinary people can already be intriguing, such resemblances become even more fascinating to fans when they involve well-known celebrities.

In the K-pop scene, “like two peas in a pod” moments—whether between idols themselves or between idols and ordinary people—are far from rare. In the past, Jimin has been repeatedly linked by netizens to several overseas “civilian look-alikes.” At times, SHINee’s Taemin or Ha Sung-woon—his close friend—have also been noted for sharing certain similarities with him.

Meanwhile, Jungkook himself has frequently been at the center of look-alike discussions online. One of the most notable cases involved Hirai Saya, the wife of actor Shim Hyung-tak. Their resemblance was reported so widely by кσяєαn media that even the two individuals involved eventually became aware of it and laughed, nodding in amused agreement with fans’ observations.

Most recently, another male idol from industry giant JYP Entertainment has become a hot topic on social media after being noted for his similar appearance. On January 5, a post on a кσяєαn online forum quickly went viral for pointing out the physical resemblance between Sungjin, the leader of DAY6, and Jungkook. In fact, this comparison has long circulated among K-pop fans, but it has recently resurfaced with renewed intensity thanks to a series of striking close-up photos of Sungjin.

Netizens expressed surprise at the similarities in the two idols’ facial structures, their large, deep-set eyes, and especially their smiles. Many referred to Sungjin as Jungkook’s “twin brother” or his “perfect look-alike.” They discuss:

- They seriously look like brothers

- OMG ㅋㅋㅋ I can't believe how much they look alike

- They could be cousins, wow

- They both have big eyes and a sharp look

- They really have a similar vibe"

- It seems people from Busan all have a similar type of face ㅋㅋㅋ

- Oh, there's definitely a resemblance. It's not a 100% match, but there's a family resemblance there

- Wow, they really do look similar, it's surprising

- Both are handsome and good at their jobs

Interestingly, in the past, Sungjin was even mistaken for Jungkook’s real older brother, allegedly named Jeon Junghyun. A “legendary” photo of Sungjin captured in profile circulated widely for years, with claims insisting that it showed Jungkook’s elusive brother. ARMYs repeatedly stepped in to clarify that the person in the photo was actually another idol—the leader of DAY6—but it took a long time for the correction to fully take hold.

Now, having moved past being mistaken for Jungkook’s brother, Sungjin is once again being mentioned for moments that cause fans to briefly mistake him for Jungkook himself. The situation has amused many fans, though some have also argued that the two no longer look as alike as before, as both have matured and developed more distinct features over time. One comment said: "Back in the day, they really did look alike. But now, one looks like a dance idol and one looks like a band guitarist, lol. Their paths are different but they're both still cool"

Beyond visual similarities and shared experiences as idols, Jungkook and Sungjin also have soмєтнing else in common: equally admirable success and promising futures in their respective careers. After completing his military service, Jungkook is currently one of the most highly anticipated figures ahead of BTS’s explosive reunion in 2026. Meanwhile, Sungjin and DAY6 enjoyed a remarkable year in 2025, emerging as the highest-grossing domestic band in South кσяєα.

According to data from KOPIS (кσяєαn Performing Arts Box Office Information System), as of September 2025, DAY6 held a total of 16 concerts in South кσяєα alone (excluding fan meetings). With more than 218,000 attendees, the band generated an impressive revenue exceeding 32.7 billion won.
