Taewoon and Zico had a cute brotherly quarrel during a live show! 

On November 10, Taewoon, Zico's older brother, held a live broadcast on 'V', with the theme of 'eating out & alone.'

Taewoon responded to the viewer comments about drinking alone, saying, "I drank alone at a BBQ place. Why did I do it? Usually, when you drink alone, it's because you just broke up with someone." He also talked about how he likes to eat alone because then he doesn't have to adjust the menu for other people." 

After eating grilled meat for a while, Taewoon asked for alcohol from the cameraman, saying, "You cannot eat meat without alcohol," but because of the broadcasting policy, he couldn't drink alcohol and had to settle with a soda instead. 

Later during the show, Taewoon was surprised to find a certain ID in the viewer comments. It was his younger brother, Zico's ID -- wooziho09. Assuring the viewers that it was Zico, Taewoon announced, "Zico is here right now!" 

The brothers then started to argue, with Zico saying, "Taewoon, I can smell your breath all the way from here," and Taewoon saying back, "Zico, please don't make a scene here." 

Taewoon soon concluded the cute fight by commenting, "Zico used to be my little brother, but whoever is more successful is the big brother (hyung)...Hyung, I apologize."
