Actor Gong Yoo's past guest appearance on a TV show meeting his high school first love went viral online.

Recently, Gong Yoo's episode of KBS' 'Love on the Air' aired back in 2002 once again garnered attention from many. 
Aired from 1994 to 2010, 'Love on the Air' was a much-loved television show that helps its guests to find the one they would like to meet after a long time.

Gong Yoo guested on the show when he was a rookie actor in his early 20s, in order to find his first love from high school.
Gong Yoo said, "I had feelings for this one girl in my high school, but I didn't have enough courage to express my feelings to her."

He then added in confidence, "But today, I will not let her go."
Gong Yoo eventually met his first love, and the two held each other's hands and reminisced their good old high school days.

Unfortunately, however, she was already in a relationship with a different person.
