Two women meet, bonded by shared experiences of heartbreak, betrayal, mistrust of men, and trauma in relationships with men. Despite being strangers, they decide to embark on a two-day, one-night hot spring trip. A staff member from a lesbian-only website—herself a genuine lesbian—acts as their guide, taking woman named Keiko on this lesbian journey to discover whether her feelings are truly real. Outgoing and sociable, Keiko gradually feels uncertain about her guest's advances, yet exchanges kisses and for the first time, touches another woman's body. In that moment, she acknowledges a woman's allure, and her curiosity toward lesbian intimacy begins to awaken. As one pleases the other, the pleasure is returned tenfold—endless ecstasy through night and morning. Touching each other's bodies, their hearts and souls grow deeply intertwined. Their feelings for each other steadily deepen. Within the special space provided by the lesbian guide, their relationship transforms into something entirely new.
