The DJs said to Junhyung, "Your face has gotten a lot smaller. Of all the times I've seen you, this is the smallest it's been." Junhyung answered, "Because I stressed a lot, I lost weight." The DJ teased, "Why? Because of a girlfriend?" Junhyung replied, "It's not because of a girlfriend, but because of the pain of composition. It was very difficult," revealing that he was stressed while working on B2ST's latest album 'TIME'.

He also revealed the meaning behind the title single, "12:30", saying, "This song compares a breakup to when the hour and minute hand at 12:30 face opposite directions. Because '12:30' is a bit of a sentimental time that evokes the exact feeling of falling, we decided to make it the title song."

When asked why B2ST always seemed to have songs about girls breaking up with them, Junhyung answered, "I think when you're rejected that feeling is the most, how can I put it, sorrowful and such, even for others." Jung Chan Woo, who was also on the show, offered a challenge, saying, "After you break up [with a girl], write a song."
