As with several other pre-debut kpop projects before them, for their debut 7Stone changed name to
TopSecret, probably as a part of optimizing the media attention if their earlier process haven't gained traction. I do think it may help here, as their first video "She" is quite nice. They have really gone for the "innocent" look that is the most common initial first phase of kpop groups, with pastelle colors and a light sound. And there is lots of fan-service, even some implied boys-on-boys love (that lipstick kiss!), so as one commenter said "Nooo i can't stan anymore groups! lol". Indeed. ;-)
