   Summary

   Hello TA Rin Itoshi,
   I will be meeting you on Wednesday at 4PM in Hallway Classroom 7B to discuss questions I've had throughout the semester. I swear to fucking god if you don’t show up im going to rip out you hair and fuck your non existent boyfriend and spread the sextape where he calls you an annoying bitch of a girlfriend to the entire school so I can morally justify your grades to me hope to see you, otherwise I will be reaching out to our professor to discuss your lack of communication with me throughout the semester.

   Best regards, Shidou Ryusei!

   Where Shidou wants to have a word with her evil TA and ends up fucking them instead. Multiple times at that!
