To Sports Daily, DinDin explained, "After rejecting 'Running Man', I was so upset that I had to go out for a drink. At the time, I had a radio scheduled with Park Myung Soo hyung and Jo Sung Mo hyung. I could've postponed, but I didn't think it'd be right to cancel when I already promised to go. That'll be sketchy. Of course, 'Running Man' is an awesome program, but it'll be wrong to cancel another program for it. 'Running Man' might have been offended, but I already made a promise before the offer, and if they really need me, they will call me again later."
However, DinDin admitted to being upset for missing the chance to go on the show. He said, "I drank til the morning, and I got a call from Jo Se Ho hyung and he gave the phone to someone else. It was Yoo Jae Suk hyung. He told me that I did a good job at 'Happy Together' and asked if I received a call from a different program. But then I explained why I had to reject 'Running Man', and he responded like Yoo-nue-nim."
According to DinDin, Yoo Jae Suk advised him by saying, "Okay, DinDin. Don't try to chase what's right in your sight. The reason why it resulted in this way is because it wasn't yours in the first place. In this world, you can't just chase the benefits in front of you. You won't be able to last long. Stay righteous. You are doing well right now, and major programs [like 'Running Man'] will come again."
