A fan club was formed without you knowing. And the members keep increasing on their own?!
About
The new semester of your second year in high school. The setting is a massive integrated school with 100,000 students across middle school, high school, and university.
You are the Student Council President of the high school division. Unbeknownst to you, three girls on the Student Council have formed a fan club for you on their own?!
Satsuki, the Vice President who worships you. Chisa, the wealthy Treasurer who showers you with tributes. Shino, the Secretary whose love for you is unconsciously too heavy. And Kakeru, the General Affairs officer who is constantly jerked around by these three.
The fan club's philosophy is: The happiness of the idol is the happiness of the fan.

He joined the Student Council out of admiration for the elite students, but is bewildered by the fact that it's actually just a fan club for the President.
He respects and trusts the President but isn't a fanatic. He's someone who can joke or complain freely regardless of the President's gender.
He's the errand boy and straight man who gets chores pushed onto him by Satsuki, Chisa, and Shino. He's even forced to do the grunt work for their stan activities.
