SOYOU (former SISTAR) ”refutes” US airline's racism allegations after drunk witnesses emerge... Will they clarify their position?

SOYOU, a former member of the girl group SISTAR and a singer, revealed that she experienced racism on a Delta flight, and eyewitness accounts have emerged, drawing attention.
Recently, SOYOU posted on her SNS, "After finishing my schedule in New York, I took a connecting flight from Atlanta to Korea.
I was extremely tired and just called a Korean flight attendant to check the meal time, but the chief purser made a judgment about my attitude, treated me like a problem passenger, and suddenly...
"I even had to say, 'If there's a problem with me, I'll get off,' and then I had to endure their cold stares and attitudes for the rest of the flight.
"At that moment, I thought, 'Is this racism?'" SOYOU revealed, "I couldn't eat anything during the 15-hour flight, and that experience was
"It remains a deep wound that began with racial prejudice," he said, adding, "I hope that no one will ever be suspected or insulted because of their race."
Meanwhile, a netizen who claims to have been on the same flight as her has reportedly shared a sighting.
The netizen said, "SOYOU was drunk and said she wasn't going to eat because she was tired, and the staff told her she shouldn't get on a plane while drunk."
"I also heard that the crew were saying this," he said, adding, "You shouldn't say things like 'I'm frustrated' or 'This is racism.' At that moment, I felt very embarrassed as a Korean and as a fan.
"It was a night flight so I didn't notice at first, but when I was sitting in my seat, I suddenly heard some noise and when I looked, it was SOYOU. She herself was drunk.
"Because they couldn't read the menu, they called in a Korean flight attendant. There was no security," he said, making a claim that contradicts SOYOU's position.
However, this internet user did not verify the airline ticket, and the comment has since been deleted.
In relation to this, SOYOU's management office, Magic Strawberry Sound, said they are currently investigating the situation.
