An online community post first shared the sighting under the title, "Lee Chae-min and Ryu Da-in came to eat at the restaurant where I work part-time today."Witness Mr. A recalled,"At an early lunchtime, an ordinary car parked in front of the restaurant, opened the door, and a handsome man and woman came in. They were so dazzling that I couldn't even look at them. As I brought them water, I saw that even with a black mask on, and even though I have face recognition disorder, it was Lee Chae-min."They added, "I was so shocked by his handsomeness. When he took off his mask, even though he was a celebrity, it was a spectacle. He even personally made Ryu Da-in a pancake and timidly asked for his autograph, to which he sweetly replied, 'It's okay.' Ryu Da-in was so beautiful right before his face disappeared that I thought, 'Wow, not just anyone can be an actor.'"
