Suika is admired by both boys and girls at her high school for her cool and attractive looks. However, Suika herself secretly admires someone who's the complete opposite of her: her cute, mellow, and unassuming classmate Kana. But she feels that cuteness doesn't fit her image and acting feminine somehow... scares her. But after Suika discovers Kana is also keeping her love for cute things hidden, they decided to form their own "Cute Alliance" where they can secretly enjoy their cute hobby together.
