Han Gain and Kim Dongjun, have they even taken genetic tests for their siblings? … Apps are also confused by the look-alikes

Lookalike actress Han Gain and actor Kim Dongjun have reunited. On the 5th, Han Gain wrote on her YouTube channel "Freedom Lady Han Gain" "The whole nation was amazed at the resemblance.
The video was titled "Is Face ID Possible for Han Gain and Kim Dongjun of the Korean TV Network? Parentage Testing, Behind the Scenes."
Han Gain and Dongjun are known for their striking resemblance.
Dongjun met his parents on his YouTube channel and this was their second time filming together. When asked how they reacted to him at the time, he said, "They laughed and asked me if I even looked like them."
"It's like looking at myself in a third person," he said. "It's like I'm in an out-of-body state," he joked. The two were amazed to find that they look more alike than their respective siblings.
Following the reaction of the fans, the two also tried their hand at Feis ID. Han Gain predicted, "I'm curious. Can I do it? I think I can open it."
Njun also expressed concern, saying, "If this were possible, it would cause a big uproar for the telecommunications companies." Next, Dongjun handed Han Gain a cell phone with Feis ID registered on it to get it recognized, but the first attempt failed.
It was a loss. Next, Dongjun tried to use the phone number registered by Han Gain, but this also failed. The two laughed and said, "This is normal."
Next, I tried the Feischange app. This time, my face had already changed on the screen, but I and everyone around me were like, "What's wrong?"
"Did something change?" "Has this changed?" "It's the same. I didn't realize it had changed." I was surprised at how similar their faces were, and confused.
The staff also prepared genetic tests for the siblings.
A maternal lineage test was then carried out, which showed a mismatch, causing laughter.
