A world that goes crazy using «swap notes» that swap when you write the names of two people and connect them with arrows. Masturbation with the body of a health teacher, SEX with the original self in a replaced state … And a female health teacher who became a captive of the replacement drags the students into a perverted replacement world! A super-dense TS story full of changes from the beginning to the end!
