Effy isn't getting along with the girls at school, and Kris has a plan to fix that. Meanwhile, Ingrid is annoyed that Yuuto fails to notice her advances, and tries to get him to realize that she's a girl.
Let's say we take this oath.
Am I the younger brother, or the older?
Wenn wir einen ablegen, bin ich
der jüngere oder ältere Bruder?
Si hacemos ese juramento,
¿yo seré el hermano mayor o el menor?
Si hacemos ese juramento,
¿yo seré el hermano mayor o el menor?
Si nous nous allions,
E se dovessimo stringerlo,
sarei il fratello maggiore o minore?
Digamos que eu faça as juras.
Serei o irmão mais novo ou o mais velho?
Допустим, я дам эту клятву. 
Я стану старшим братом или младшим?
