B1A4's Baro is famous for his rap and his great role in the group. He has been successful as a member of the boy group. In 2017, his sister Cha Yoon Ji will be making a debut. Everyone is wondering about his thought on his sister debut.

As mentioned at the interview, he said that his sister has 6 years of training and it is longer than Baro himself. Regarding to his personality to be protective brother, he actually trusts her sister as a whole, according to Allkpop. He has been asked to take a video of her dancing and singing and he thought that she is so wonderful, although he only says that " she is good" to his sister.

Due to his busy schedule, he cannot support his sister completely as he wants. But he always wants the best for her. In the family, his sister has been known to have a great talent. Cha Yoon Ji has been learning to play piano, sing and dance. She is a full package of a new star.

As a brother, B1A4 shares thought and concerns on his sister impending debut to be quite supportive. But one thing can be a concern for him. His sister is a girl who looks so tough at front but she is quite soft. She tends to look stronger that she is actually quite sensitive inside, according to Kpopfans.

Baro thinks that her personality can be a concern since there will be many events or people in the  entertainment industry that can hurt her. But as his brother, he will always try to prevent that. He tries to always be there when his sister needs her.

Wow, that is a sweet thought of B1A4 shares thought and concerns on his sister impending debut. Hope Cha Yoon Ji will lead to have a good career ahead.
