This is Joo Se Young and she will go by Sey and she is the oldest in the group according to YG Entertainment at 20 years old (22 years old in Korea due to being early born). She is also the main vocalist of the group and has trained under YG Entertainment for 2 years, but before was a JYP Entertainment trainee for 1 year and 6 months.

You may have seen Sey as she has appeared on 'InStyle' and ' Dazed' magazine. Sey was also in a band and was the main gutairist and singer. Currently Sey is attending Korea National Univeristy in her 2nd year as a dance performance major, but actually graduated from Seoul Science School! Sey could be really smart then like some idols who major in the science field. 

We wish Sey good luck in debuting with #Hashtag! This means the last member is yet to be revealed and it seems that member will either be the leader or this group will have no leader. Hopefully YG Entertainment releases the fifth member soon!
