Actor Choi Tae Joon recently opened up about a really embarrassing yet unforgettable experience he had as a student.

The 32-year-old star, who previously appeared in dramas like Piano and Padam Padam: The Sound of His and Her Heartbeats, told the embarrassing story in an interview.

In his early twenties, Choi was on a bus and met a pretty girl who inspired his imagination, as in a scene in the romance film Before Sunrise.

Finally, he gained the courage to ask for her number, only to be rejected. "I have a boyfriend," she told him.

Things took a turn for the worse when the woman failed to disembark from the bus, as he was expecting. Instead, she stood next to the door.

Choi had to put up with an uncomfortable 30-minute ride. He said, "My ears were red the whole time," he recalled, reflecting on the humiliation of the encounter.

Choi swore on that day that he would never again ask a stranger for a number. He has since put it behind him to go on and is now happily married to actress Park Shin Hye. They welcomed a son together in May 2022.

The two actors are currently starring in the KBS weekend drama "Iron Family," while Park was just seen in the recently concluded SBS drama "Judge from Hell."
