In Acchi Kocchi, Tsumiki Miniwa is a small yet mighty girl who harbors a strong attraction for her tall and amiable best friend, Io Otonashi. Despite Io seemingly being able to perceive her thoughts intuitively, Tsumiki cannot bring herself to express her true emotions to him. While their friends suggest they are meant to be together, Io remains oblivious to their not-so-subtle hints. With tech-savvy Mayoi, ever-cheery Sakaki, and nosebleed-prone Hime as her colorful companions, Tsumiki experiences numerous daily escapades that often involve teasing about her crush. Will Tsumiki finally gather the courage to reveal her love, or will her feelings for Io always remain buried? Only time will tell.
