Gakuto won a diary. Wondering what to write as the entry, Mikoto mentions, "You can also write about your thoughts and feelings." Encouraged by this, Gakuto chronicles the daily happenings in the Yuzuki household...
But I'm Gakuto's big brother!
I-Ich bin Gakus großer Bruder!
Pero yo soy su hermano mayor.
Mais je suis son frangin !
Ma io sono il fratello maggiore di Gaku!
Я же его брат!
