B1A4 is a South Korean boy band under the management of WM Entertainment that debuted in 2011. The group's name has a connection with the members' blood types. Members Jinyoung, CNU, Sandeul and Gongchan are type A and member Baro is a type B, hence the numbers 4 and 1 to make the group name "B1A4". "Be the one All for one“ is another explanation concerning the group's name meaning that they'll do their best as what everyone expects them to.
