Yuuki Akio, a popular and cheeky boy in his final year of high school, is deeply in love with his junior of one year, Ayakouji Chiharu.
Chiharu is easily flustered and lacks self-confidence, and is often the target of Akio's teasing. She is also deeply in love with him.
However, both of them lack the courage to confess to each other and their daily lives of barely crossing the border of love continue.
