Haruka Takayama and Yuu Sonoda, inseparable best friends since middle school, had always dreamt of attending Misato West High School together. Unfortunately, fate had other plans as they found themselves seated on opposite ends of the classroom even though they were in the same class. To add to their dismay, their school was scheduled to close down in three years, leaving them as the last batch of first-year students. But Haruka was determined to stick by Yuu and create unforgettable memories with her. Over time, Haruka's envy for Yuu's carefree personality grew as it drew the attention of their female classmates. In a bid to soothe her best friend's insecurities, Yuu decided to share an intimate and passionate kiss with Haruka in an empty classroom. This act only cemented their bond as "special friends" while also presenting new challenges and depths to their relationship.
