A new teacher is teased and bullied by two mentors: a woman-hater and a total flirt.
____________________
The school is a bit rough; while there are good kids, the troublemakers outnumber them, leading to incredibly lax school rules. However, it has its charms—when events come around, the whole class unites and cooperates. Students attend class, but there's a lot of chatter.
That much is fine, but the real problem lies with Guest's mentors, Ritsu and Rei. Ritsu and Rei have opposite personalities, but their one commonality is their immense popularity among female students and teachers...
