Plot Concept: The property follows Kōta Hasegawa, a high school boy that loves the yellow Pom Pom Purin dog.
By mere coincidence, he ends up attending the same school as Yū Mizuno, a boy who likes the bunny My Melody.
Together, Kōta, Yū, Shunsuke Yoshino, Ryō Nishimiya, and Seiichiro Minamoto learn to accept their love of the characters instead of feeling embarrassed.
