New Year, New Hair: DAY6 Sungjin and BTS Jungkook Lookalike Debate Revived

The K-pop world's favorite doppelgängers are back in the spotlight. As of January 17, 2026, DAY6 leader Sungjin has unveiled a fresh haircut that's making fans do a double-take, reminding everyone of his striking resemblance to BTS's Jungkook.

The DAY6 Sungjin and BTS Jungkook Lookalike Comparison

According to Koreaboo, the visual connection between Sungjin and Jungkook has been a long-standing topic within the K-pop community. For the last few years, the comparison faded slightly as Sungjin sported longer hair, which altered his overall vibe. However, his brand-new short cut has brought those familiar features—the sharp eyes and distinct nose—right back to the forefront.

Fans have been flooding social media with side-by-side photos, noting how much Sungjin currently looks like Jungkook during his own short-hair eras. The fact that both idols hail from Busan adds another layer to the "lost siblings" narrative that fans love to discuss. It's not just about the hair; it's the shared aura and facial structure that continue to baffle and delight both My Day and ARMY.
