Kanon Hazuki can be considered a typical teenage delinquent, often tardy and avoiding classes by seeking refuge in the school nurse's office where she passes time chatting with the male nurse, BJ (Kuroanada Jun).
Tamaki Daichi has a penchant for filming subjects that fascinate him, overlooking any possible consequences. His friend Kihou Tomoka attempts to shake him out of it whenever she spots him lingering when he should be somewhere else.
One day, Daichi's attention is captured by Hazuki while she stands atop an adjacent building's roof. After obtaining information from Tomoka, Daichi decides to visit the nurse's office where Hazuki occasionally dozes off. Hazuki awakens to discover a stranger filming her and even referring to her as "adorable" while she sleeps with her thumb in her mouth. Consequently, she agrees to let him keep the footage under the stipulation that he uphold her secret.
