Saki watches her sister with Kaname and knows exactly what she's lost before she even had it. Starting college is supposed to be the escape route, but the show understands that moving on isn't about finding someone new, it's about becoming someone who doesn't need him anymore. One episode. No dramatic climax. Just the quiet, specific pain of choosing yourself over a ghost you invited into your life.
Saki carries a secret into college: she is in love with Kaname, her older sister Noriko's boyfriend, and the feeling fills her with guilt. She does not know the two have already split up. Hoping to start fresh, she sees college as a chance to leave those feelings behind and find a new love. But Kaname turns out to attend the same college, and she ends up recruited into his video club. There she is chosen to work on a project with another student, Daichi, and finds herself drawn to him even as thoughts of Kaname refuse to fade. The result is a romance OVA about guilt, longing and the difficulty of moving on.
