Haruki spends most of his time with friends and fellow classmates Airi and Ayana. All seems well, that is until Airi and Ayana form separate clubs, the Mechanical Science Club and the Chemical Science Club. The two vie for Haruki's attention and hilarious chaos usually follows all attempts to make him join.
