The members of B1A4 appeared as guests on the September 16 episode of JTBCs Ask Us Anything. During one of their talk segments, Baro revealed that CNU had once made him cry, which Sandeul and Gongchan backed up by saying that they too had been scolded by CNU a lot as trainees.
After hearing this, CNU shared the story behind making Baro cry. CNU said, During our trainee years, Jinyoung and I were 20-year-old adults so we would wake up and go to the practice room. Meanwhile, they [Baro, Sandeul, and Gongchan] were younger so they went to school. One day, Baro came back bragging that he got a girls phone number. It made me so angry!
