Yuki features in two separate stories of the Cream Lemon anthology. In "Happening Summer" (episode 9), she is a schoolgirl entangled in a love triangle. Yuki harbors romantic feelings for Akira, her older sister's boyfriend. Her attempts to gain his attention culminate in a traumatic encounter where Akira attempts to assault her. The altercation escalates until her sister intervenes, confronting Akira and severing their relationship. In "Summer Wind" (episode 22 of New Cream Lemon), Yuki anchors a self-contained romantic narrative focused on a bittersweet love arc.
