WM Entertainment recently announced that B1A4 Baro's younger sister, Cha Yoon Ji, will be making a solo debut in 2017. Baro shared thoughts about Yoon Ji stepping a foot into the K-pop industry in an interview with News 1. 

Baro first said, "She's been a trainee for almost 6 years. That's longer than me. Our family has supported her in the field of music since she was young, so she played the piano, sang, and danced since she was a baby. She's outstanding so I'm not worried in regards to her talent. Even if I see her from a strict oppa perspective, I'm not concerned about her talent but as for her personality, she tends to look tough on the outside when she's actually soft. She's the type who cries by herself in the back after getting yelled at by mom. There are a lot of things that can hurt her in this industry so that is something that worries me."

He continued, "I have to take good care of her but I'm also busy nowadays so I barely have the time to see her. As an oppa, I always want to cheer her on and think about how I can be supportive. Talent wise, there's nothing to criticize because she's outstanding in both singing and dancing. I rather need to learn. So the biggest concern of mine is how I can be supportive to her." 

"She's going to be by herself so she'll be lonely but I want to be there for her. I really believe she'll do well. She always asked, 'Oppa, take a video of me dancing', and showed me her dance and all I had to say was, she's good. But I'm not the type to express that to my dongsaeng."

Lastly, Baro shared an encouraging message to his sister, saying, "You are now starting social [adult] life so nothing's going to be easy. But oppa will be by your side and give you support. Let oppa know when you are struggling. Yoon Ji, you are far more outstanding than anyone, so have confidence and I hope you always work hard."
