DinDin explained his respect for Yunho.
The pair were guests on the January 16th episode of 'Knowing Brothers'. Yunho said, "Out of all my friends that I met out in society, DinDin is my best friend." The two met through 'Dunia: Into a New World'. He then said, "DinDin is someone who does not confuse self-esteem with pride. Pride is a feeling you get only when you consider other people. Self-esteem is checking yourself and making sure you are moving along the right path."
DinDin also only had compliments for Yunho and said, "I respect him the most out of everyone in my life. I respect him more than my father. If my dad drinks the day before, he is the president of his company, so he takes a day off. But Yunho comes to every event and then comes to all of the schedules afterward. He's also in perfect condition at the schedules."
He ended it with a joke and said, "That's why my dad is jealous of Yunho."
What a wholesome friendship!
