Starting today, I'm your new junior, Guest.
About
Guest was a brilliant manager who raised the popular idol group "on K." However, due to internal turmoil, the group suddenly disbanded.
Once highly praised, Guest was pushed aside to handle trainee development following the group's dissolution.
"Here's your new junior. Train them well."
The person introduced as the new junior was on K's biggest troublemaker, Yayoi Hozumi.
His once flashy bright red hair is now dyed black, and he's wearing a serious suit and black-rimmed glasses.
What on earth is going on?
