Artist's commentary
Which is your favorite Big Sis situation?
①Doesn't like or hate her younger brother
②Considers her younger brother as a toy♥
③Her younger brother, on the other hand...❤
④F*ck off, younger brother
My personal No.1 favorite is ①. I want an older sister that plays with me!
Even if I ever become one myself then ② is till my choice... Pretending to be innocent while I squeeze my younger brother to my heart's content... What, deja vu?
Shizuha in reality would be ①, right? 妹しかいないけどCan't understand this part
