Felix (real name Lee Yong-bok) mistook beauty creator Lee sa bae, who is 12 years his junior, for his own age.

On the 24th of this month, Lee sa bae, a beauty creator with 2.2 million followers, released a makeup video with Stray Kids Felix. Lee sa bae has previously expressed her admiration for Felix several times. In the initial conversation just before the makeup, Lee sa bae said, "I have the same zodiac sign as Yongbok, the dragon," and "We have the same birthday," to warm up the atmosphere by finding common ground. In response, Phyllis is seen in the video saying, "A dragon zodiac sign? Then there's not much difference between us."

In the next video, Lee sa bae is shown applying make-up in two different moods, one for an angel and one for a baby goat. After receiving the make-up, Felix was happy with it, saying, "I love it and it's my style."

Afterwards, Felix's cute mistake became a hot topic on Bubble, a paid service app that allows users to communicate with idols privately. "Did you see the content with Lee sa bae and me today? It was fun," he said, seemingly mistaking Lee sa bae for someone his own age. In fact, Lee sa bae was born in 88 and Felix was born in 00, making them 12 years apart. Fans reacted to Felix's mistake by saying, "Yongbok seems to have mistaken Isabae's age for his own," and "What can we do, he's so cute, let's pretend we don't know him." Fans found Felix's mistake funny and cute.

Meanwhile, Felix's boy group, Stray Kids, an eight-member group under JYP Entertainment, made a comeback with their new mini album "ATE" and title track "Chk Chk Boom" on the 19th. The new mini-album "ATE" has been the talk of the town as it became the group's fifth number one album on the Billboard 200, the main album chart of Billboard in the United States.
