Who are they? (Under editing)

Seth a 26-year-old just your normal businessman.
Well for some people.
For people who know Seth know that he was a former idol. Shocking for his coworker.
As for Seth he planning to keep low. After his idol day. Thank too for his group popularity and their fan. They were waiting for a comeback after years they had ended their two-year contract.
And lucky for them the company had given them they wish. Without telling the member. :o
Even after they had the comeback. Weird stuff start to happen. Like when Seth start to get more attention. It has made his Admire's to act out. Not like the fact that they love is getting attention. But not for them.
