B1A4 guested on 'Kim Chang Ryul's Old School' on December 7, where Baro was asked when he's happiest.
The idol replied, "I'm happiest when I'm checking my bank account," making everyone laugh with his honesty. He continued, "I check once every three months, which makes me happy," satisfying Kim Chang Ryul, who had asked the question.
Baro added, "I'm happy when the response to my hard work is good. This time around, I dieted a lot, so I like hearing that I lost a lot of weight or that I look handsome. I also changed my hair color, so I'm happiest when I hear that the color is pretty."
