This is a first-time shoot documentary featuring an amateur woman and an amateur director. It's a secret from her fiancé. The director is a tutor from her school days. She ends up starring in an AV after being seduced by an amateur man she met online. She's from Chiba Prefecture, both in birth and upbringing. Yuu, who has always been quiet and composed, shows a side of herself that's both shy and confused in front of the camera, a talent that surpasses even that of a big-name AV actress. It's truly moving.
