Count on me

"Today you are going to have a new band mate .... hope you guys gonna like him ... well his name is Jung hoseok ..."

In which BTS had 6 members but suddenly they found a new member is going to join them soon .. named Jung hoseok...
The six member surely didn't want this to happen ...
Hence they made it difficult for the new boy to be in the group ...
But what happen when the boy get tired and left the band itself..
And they feel how important that boy is for them, how badly they misses the sunshine smile ...
Will they make out to find hoseok and will he be in the group again ..????
