Honestly never heard her name so much until she joined HYBE and has gotten used over and over for media play to hype up the new group to look like the second coming of SM GG. She is one person in a creative team for designs but the articles make you feel like she was part of managing every SM group. I am baffled by the comments that say things like "I hope we get a second SNSD/Fx for MHJ group". I always thought these comments were stupid when they were about an upcoming group from the same company (like aespa pre-debut expected to be like SNSD) but even that sounded more logical than one person who was part of the creative team.
on topic though. Those designs are gold. Don't know how much she contributed in SM overall but she is definitely talented.
