Valentine's Day Time.As the students prepare for their entrance exams, Nagisa is led to consider becoming a teacher when having a conversation with Sakura during their tutoring session. Meanwhile, Karma and Nakamura notice that Kaede hesitates to give Nagisa a box of chocolates for Valentine's Day, so they show her how the other female students take on this approach to the other male students. However, when Kaede works up the courage to do so, she is ultimately unable to confess her feelings for him. Elsewhere, Karasuma and Irina have a date together, discussing the likelihood that Koro-sensei will not stop being targeted simply because of his reduced chance of exploding. Also, Gakuhō offers Koro-sensei to continue teaching the class during the next term, but Koro-sensei considers resignation instead. Karasuma suggests Irina to work for the government due to her expertise, and he hints that she should move in with him.
