15 K-Pop Idols Who Are Unrelated But Look Alike They'll Pass As Twins

Some K-pop idols are mistaken to be twins or siblings because of their many similarities in visuals and personalities.

In May, a TikTok video went viral for its content about K-pop male and female idols with a striking, uncanny resemblance.

Here's a list of male and female K-pop idols who look very much alike that they could pass as twins or siblings separated at birth.

1. Itzy's Yeji and Stray Kids' Hyunjin

Aside from being company siblings under JYP Entertainment, Itzy's Yeji and Stray Kids' Hyunjin have the same surnames. They were even referred to by some fans as "Hwang Twins."

In a fan video edit under the Twitter thread "Rumors you have ever believed as a K-popper," the uploader shared they used to believe Yeji and Hyunjin were siblings because their features are very much alike.

2. BTOB's Minhyuk and Tomorrow X Together's Soobin

Fans started to notice the uncanny resemblance between BTOB's Minhyuk and Tomorrow X Together's Soobin when the latter was an MC (Master of Ceremonies) at "BTOB 4U" in November 2020.

Despite being born a decade apart, fans noticed they could pass as twins because of their similar features and smiles.

3. Le Sserafim's Kazuha and Suzy

In a past TheKstarNextDoor interview, the MC mentioned that Japanese member Kazuha of South Korean girl group Le Sserafim looked like Bae Suzy, to which she humbly replied, "Only a little bit."

Because of their similar visual features, they were once nominated as K-pop idols who could pass as mother and daughter.

Seventeen's lead vocalist Woozi previously appeared on BTS' Suga's online show "Suchwita" in May. His hair was even styled like Suga's to highlight their resemblance.

5. Itzy's Ryujin and Blackpink's Rosé

Aside from looking alike in some photos, Itzy's Ryujin and Blackpink's Rosé also seem to have similar facial expressions and personalities.

A fan added that fourth-generation idol Jay from Enhypen would make them triplets.

On "I-Land," Seventeen member Hoshi also noticed that Jun and Jay are look-alikes and asked them to dance to Seventeen's song "HIT" together. Dancing next to each other highlighted their similar facial features even more.

8. Twice's Mina and Enhypen's Sunghoon

In March 2022, an Enhypen fan account posted a Twitter thread on the "twinification" of Twice's Mina and Enhypen's Sungwoon.
