The opening episode establishes Haruka Takayama and Yuu Sonoda beginning a secret kissing practice as their unique bond, which drives nearly every subsequent episode through jealousy, confessions, sleepovers, festivals, and graduation arcs explicitly involving their relationship and parallel pairings such as Shizuku and Kotone. This structure leaves little room for traditional plot elements, making the yuri dynamics the sole foundation. Episodes repeatedly foreground secret lesbian intimacy, jealousy, and confessions as central conflicts and resolutions, with multiple episodes featuring direct plot points like phone kisses, mistaken identities leading to kisses, and Mitsuki's love confession to Haruka.

Without any external social justice framing, the yuri focus itself constitutes the ideological content, resulting in a series where progressive themes of same-sex relationships intrude upon and ultimately define the entertainment experience to an overwhelming degree. This approach compromises broader appeal by sidelining conventional narrative arcs in favor of repetitive romantic explorations.
