As usual, Kinugawa and Yufuin are walking to Binan High School together as friends. But after a stop at the convenience store, Yufuin suddenly gets angry at Kinugawa and yells at him. A rift forms between the two, and soon a panic develops over them potentially leaving the Defense Club. Yumoto works blindly to try to get the two to make up, but Naruko and Zaou rebuke him for it. Will Yufuin and Kinugawa ever make up?!
No, no. It's my fault for secretly 
looking at your cell phone.
Nein, nein. Es ist meine Schuld,
weil ich auf dein Handy geguckt hab.
No, no. Es mi culpa por husmear en tu teléfono en secreto.
No, no. Es mi culpa por husmear 
en tu móvil en secreto.
No, no, è stata colpa mia per aver 
guardato di nascosto il tuo cellulare.
Não, não. É minha culpa por
 ficar olhando no seu celular.
