SGRS-010 - Fallen Teacher: The Secret Private Life Behind the Collapsed Classroom

I was drawn in by the title. The way Tsumugi Serizawa and Natsuko Kayama are threatened by delinquent students and eventually corrupted is quite impressive. The fast-paced story is worth watching, though the sex scenes lack realism. I give it a high rating for the gap between the serious-sounding title and the surprisingly pop-style content.
