「すれ違いの（課外）授業」 (Surechigai no (Kagai) Jyugyou)
"(Extracurricular) Activities While Passing Each Other By"

Even with almost no references to anything in the past five episodes, I think that this has been the best episode thus far. I'm sure that my bias for slice-of-life elements and high school romcoms is butting its head in here, but I think this show flows a lot better when it's not trying too hard to be serious.
