He made a surprise appearance on 'Human Theater'. I have to watch this! Haha.

Park Ji-hoon, who started as a child actor and is now thriving as both an idol and an actor, is Lee Ru-da's role model. As soon as Lee Ru-da saw Park Ji-hoon, she burst into tears she had been holding back, and Park Ji-hoon smiled and greeted her warmly.
With curiosity mounting over what kind of encouragement and advice Park Ji-hoon offered to Lee Ru-da, it is said that it will be revealed on 'Human Theater' on the morning of the 21st!
