Please Go Home, Miss Akutsu!

Living alone, Ooyama is a meek high schooler whose peaceful existence has recently been disturbed. One day, his classmate Riko Akutsu abruptly invited herself over and marked Ooyama's bedroom as her designated post-school hangout. Indulging in his manga stash, snacks and drinks, the troublesome delinquent enjoys lounging in his bed for leisurely naps. Ooyama finds himself unable to persuade Akutsu to depart, as she continues to frequent his home every single day with her provocative presence causing a stir within him. However, as time passes, their unordinary relationship evolves from mischievous taunting to a familiarity with each other that neither could have predicted.
