On August 18, Seolhyun updated her Instagram profile by uploading a link without any other information. The new link on Seolhyun's Instagram opens up to a YouTube channel called, "Brilliantly by Seolhyun."
It seems that Seolhyun will be uploading her vlogs and various other content in the future. It has not been long since the YouTube channel has been opened but already has over 2,000 subscribers despite not having any videos uploaded yet. It is expected that there will be more subscribers as soon as Seolhyun uploads her first video.
Meanwhile, Seolhyun has been also embroiled in the AOA bullying controversy when Mina stated that Jimin had bullied her during the time she was promoting with the group and accused the other members of spectating and neglecting the bullying.
