"Thank you for taking care of me." Actor Kang Kyung-joon's son jeong-an thanked Kang Kyung-joon for his sincerity. On KBS2 The Return of Superman' broadcasted on the 6th, Kang Kyung-joon, jeong-an and Jung Woo Sambuja's Gyeonggang Line trip was joined by mother Jang Shin-young. On the morning of the second day of the trip, Sambuja, who stopped by the restaurant, looked particularly tired because he had not been able to sleep properly due to the change of bed. Sambuja overcame his sleepiness and began to eat. However, Jang Shin-young surprised everyone by appearing behind Kang Kyung-joon. Jang Shin-young came to Gyeonggang Line directly because he was worried about Sambu who went on an unplanned trip. Kang Kyung-joon laughed at the children who saw Jang Shin-young as soon as he saw them, saying, "I think I became a criminal." In an interview with the production crew, "I was like me and the children were like beggars. "Thank you so much for coming," he said with a smile. Since then, Kang Kyung-joon and jeong-an have spent only two hours. First of all, I had a dynamic experience on the sea sky bicycle at 20m above the sky. Kang Kyung-joon was terrified and shouted, while jeong-an remained relatively calm and overcame his fear, but suddenly jeong-an's bicycle did not go forward, embarrassing the rich man. It turned out that jeong-an turned the bicycle chain too fast and the chain fell out. Kang Kyung-joon asked jeong-an for help, saying, "It's my wedding anniversary soon, so please help me do The Speech. I think I'll die if I don't take it." Kang Kyung-joon bought a flower and told jeong-an, "Did you give me flowers on Mother's Day? "Chung-an said," I did not give it to me when I was a child, so I did not give it to me. I was a child until the first year of high school. "Kang Kyung-joon said," Let's go. " Kang Kyung-joon gave a speech to the event, such as putting a red carpet on the caravan, and thanking jeong-an for saying, "It would have been a big day without you." jeong-an appeared with a cake and sprinkled flowers when Jang Shin-young came, and then Kang Kyung-joon appeared and said, "Happy anniversary. I love you." The birthday present was a set of children's princess collections consisting of a crown, a necklace, and a magic stick, and Jang Shin-young laughed at it. Kang Kyung-joon said in an interview with the production crew, "I thought that jeong-an could not come to me, but I think it was very big through this trip. I still think of jeong-an as a six-year-old child, and I regret that I was young. "Jung Woo is also good to her mother and she is so beautiful. I think I should spend more time with jeong-an." jeong-an also said, "I am scarce, but I am grateful that I can see my heart to take care of me." Kang Kyung-joon expressed his heartfelt gratitude.
