Zoku Sensei no Okiniiri! (2006)

Misuzu gets threatening mail, it's author claiming to know her secret. Her secret is her pupil and underaged lover Nishidou. Nishidou wants to be with her but she hesitates because he is her ward and things are quite complicated, therefore she wants to wait for his graduation. But they have a greater problem than threatening mails, because Misuzus former boyfriend and Nishidou's brother won't let them be.

This manga is just as bad as the prequel. Both main characters behave like little kids, the story did not end properly and it just wasn't worth reading it. There was no development or anything. And I couldn't find any sequel to this, so the story isn't even finished.
