"Wonderful Days" Kim Dan Yul tried to organize the relationship of Hong Wha Ri and Choi Kwon Soo and how they call each other.
On the episode of "Wonderful Days" broadcast on April 20th, Kang Mool (played by Kim Dan Yul) realized that Dong Joo (played by Hong Wha Ri) and Dong Won (played by Choi Kwon Soo) were not their uncle but their cousin's sibling.
On this day, Kang Moon was angry and said to Dong Won, "Are you seriously two years younger and made me carry your bag and your bread and even your supply material?"
At this, Dong Won bowed 90 degrees to Kang Moon and gave him a badge and said, "Bro, don't be so upset. It's not good for your health. If I had known you were my cousin and older brother, would I have been so immature? Let's maintain a good relationship as older and younger cousins" as he held out his hand to shake.
Kang Moon refused the handshake and said, "That's okay. I will show the revenge of blood from now on" showing a cute vengeful spirit.
At this, Dong Soo who appeared said, "I still can't acknowledge the relationship with Kang Dong Hee so I can't call you older brother" and Kang Mool said, "Right. What importance do names have anyway. Do whatever pleases you" and showed a different attitude than towards Dong Won and drew laughter.
