APNS-313 Gang rape of intern teacher

One day, Mari, a teacher, visited the house of Yugo, a student who refused to go to school in her homeroom's class, with her husband and a Philosophy teacher. The school abandoned Yugo because of his problematic behavior, but despite his protests, he visited his home. However, as soon as Yugo welcomed Mari in, he made Mari and Tetsugaku drink tea laced with sleeping pills, and knocked Mari out in front of Tetsugaku.
