Saki Sakisaka, a graduating high school student, secretly harbors feelings for Kaname Kazame—her older sister Noriko's boyfriend, unaware their relationship has ended. Hoping college would distance her from this turmoil, she instead enrolls at Kazame's university. During orientation, Kazame recruits her into his video club to film her, while fellow student Daichi Tachibana, concealing his own affection for Saki, also seeks to document her.

Torn by perceived betrayal of Noriko, Saki suppresses her emotions and avoids confronting Kazame. Her internal conflict unfolds within the video club as she navigates complex feelings toward both Kazame and Tachibana. Resolution arrives when Noriko reveals the prior breakup, liberating Saki from guilt. This clarity allows Saki to acknowledge her feelings for Kazame, forging a mutual romantic bond.

Saki's family includes parents and sister Noriko, though her upbringing remains unexplored. Her narrative centers solely on an emotional journey through unrequited love, misconception, and resolution via direct communication and clarified circumstances.
