Izumi-kun is out sick from school. Shikimori-san learns that Izumi-kun asked Inuzuka to take notes for him, causing her to glare daggers at Inuzuka in envy. Yes, Shikimori-san sees Inuzuka as a rival. When the two of them go to Izumi-kun's house together to take the notes to him, Hachimitsu secretly follows them, and one little word that slips from Shikimori-san's mouth leads her to deduce the reason for this perceived rivalry... On another day, Shikimori-san is at the mall with Nekozaki, where they run into Kamiya-san and invite her to hang out with them.
Wait, so all those times she's 
treated me like a rival...
لحظة، إذاً كلّ تلك الأوقات التي كانت
...تعاملني فيها كمُنافس
Hä … Kommt ihr Konkurrenzverhalten
die ganze Zeit über etwa nur daher?
¿Eh? Entonces todo eso
de que me veía como un rival…
¿Cómo?
¿Entonces ese rollo de ser su rival…?
Hein ? Donc, selon toi, c’est pour ça
qu’elle me traite comme un rival ?
Eh?
Espera, então todas aquelas vezes
que ela me tratou como um rival...
Чё?
