Abikura and the photography club arrive at the fireworks festival. Ms. Hiwamura fully enjoys the summer festival, but her yukata becomes disheveled, and she has to go to a deserted forest to have Abikura fix it for her! Abikura is flustered to see that the teacher isn't wearing any underwear. Furthermore, when the teacher becomes dizzy, Abikura supports her, and the feelings she has been holding inside for so long finally spill out.

Abikura-kun injured his dominant hand protecting Ms. Hiwamura. Feeling responsible, Ms. Hiwamura
declared that she would "take care of him one-on-one," and for some reason began cooking wearing only an apron! She even tried to help him with his bath, attempting to wash not only his back but also his "front." After a scuffle, Ms. Hiwamura's bath towel slipped off, and she fell onto Abikura-kun...!?
