This work unfolds a dramatic story depicting the affair between a veteran pilot nearing retirement, Imai, and a young, beautiful flight attendant, Nagisa. Nagisa's acting is among the best in the series, and the story's quality is top-notch. As a brainwashing piece, its completion is highly commendable, especially the depiction of the brainwashing process. However, extending the period of sanity or adding sub-stories about the erosion process would have added more depth. If the brainwashing scenes accounted for more than 40%, it would be a flawless five. The sight of wearing colored contacts and being in a daze, as well as the depiction of Rensei, who was brainwashed, brainwashing others, are also highlights. For the next work, we hope to see developments where women are brainwashed instead of men. A must-buy for series fans!
