B1A4 Ultimate Fan Guide

If you are the type of a KPOP fan who likes bright and vibrant pop music, then you should start listening to B1A4. The group has been the epitome of “colorful pop”. They managed to pull off a very light concept without people questioning their preferences.

B1A4 is a South Korean boy band formed under WM Entertainment. The group had their debut on April 23, 2011 with the song “O.K” with five members: Jinyoung, CNU, Baro, Sandeul, and Gongchan. However, recently their contract with their company has expired and only CNU, Sandeul, and Gongchan renewed their contracts. Jinyoung and Baro decided to leave WM Entertainment. There was a long discussion about how the group will continue promoting. After the discussion, it was decided that B1A4 will continue as a trio for now with hopes that there will be an opportunity for the group to promote with five members.

CNU is considered as the mother of the group. It’s not really about his long hair but CNU likes taking care of his members. He was the last member to be added to the group before they debuted. CNU revealed that his ideal type is a motherly and mature woman. He also revealed in one of his guest appearances that Krystal is one of his ideal types although she’s not really motherly. He also likes Go Hyunjung because he gets the feeling of maturity.


Name: Lee Junghwan

Sandeul is really close to his members. He once set the wallpaper on his laptop to Gongchan’s picture. Aside from promoting as a group, Sandeul has also successfully debuted as a solo artist in October 2016 with the EP “Stay As You Are”. Sandeul is also very close to BTS’ Jin and VIXX’s Ken. They actually have a group chat with other idols born in 1992.


Name: Gong Chanshik

Birthday: August 14, 1993

Position: Lead Dancer, Vocalist, Visual, Face of the Group, Maknae

Out of all the members of B1A4, Gongchan is the best when it comes to fan service. He knows what will make the fans’ hearts flutter. He’s also a brainiac. He’s very good at math. Gongchan also has a very known close relationship with VIXX’s Hongbin. They appeared together in a variety show called “Celebrity Bromance” where they went on a date as friends.

Indefinite Hiatus


Name: Jung Jinyoung

Birthday: November 18, 1991

Position: Leader, Lead Vocalist

Jinyoung is a really talented person. Aside from being an idol, he also writes and composes songs not only for B1A4 but for other artists as well. This is one of the biggest reasons why he is my bias. He wrote songs for their sisters at WM, “Oh My Girl”. He also participated as a songwriter during the first season of Produce 101, composing two original songs for the contestants to perform. Jinyoung is also a successful actor and has appeared in Korean dramas like “Persevere, Goo Haera”, “Warm and Cozy”, and “Love in the Moonlight”.


Name: Cha Sunwoo

Birthday: September 5, 1992

Position: Main Rapper

Aside from Jinyoung, Baro is also another successful actor from the group. His most notable appearances in dramas include “Reply 1994”, “Angry Mom”, and “Manhole”. He likes to wear caps and hats and says that it is what keeps him confident.


While the group has not had any current activities as a three-member group, there are a lot of reasons why you should start listening to their songs and watching their past shows.

  • Amazing vocals. The group houses one of the most beautiful voices in KPOP. Sandeul has an incredibly wide vocal range. He joined King of Masked Singer before and has stayed as the King for a while. Along with the other members, the group has been dubbed to eat CDs for meals.
  • While B1A4 debuted as a group with a colorful pop genre, this has not limited them from trying other concepts and genres. This is one of the reasons why I like them. They have done many concepts ranging from light pop for “What’s Happening?” to elegant men for “Sweet Girl”. I personally have a connection with the song “What’s Happening?”. We danced a cover of it and performed in a local KPOP competition and we actually won. Another B1A4 song that I like is “Baby Good Night”. It’s a very upbeat song but when you learn the lyrics, the song actually talks about a guy sending his girlfriend to sleep so he could go out and play in clubs. It’s not a very good message to relay to the audience but I like it because of its wit and unique message.
  • Most of the choreographies of the songs of B1A4 are under-appreciated. Many people might think that the dances are simple but they surely have impressive footwork. We’ve covered a lot of their songs and I must say that their song “Tried to Walk” has one of the hardest choreographies we ever did. “What’s Happening?” might seem to have a playful choreography but there is a part at the very end of the song where the dance involves really fast movements. It took us about a week to master those moves.
  • Countryside Roots. Most idols come from big cities. The members of B1A4 actually came from different provinces in Korea. Because of this, they have become inspirations for younger idols to reach for their dreams. Just because they live in the countryside doesn’t mean that they have no shot at being idols. If B1A4 can make it, they can too!

I’m actually missing B1A4. I was a little saddened by the news that they will not be continuing as a five-member group as of the moment. Jinyoung is an essential part of the group and I’m thankful that he brought the group to where they are now. I’m just hoping that they do decide to come together again as five and promote. That would mean more songs for us to do dance covers!
