Sakuya-san Attack
Summary: Sakuya will pat your head if you are sorting out books.
Saku [...](feeling satisfied)
Ko [...Ummmm, Sakuya-san?]
Saku [My?]
Ko [Uh, Uhmmm,, I-Is there anything you want?]
Saku [It seems I forgot to stop time]
Ko [Eh]
Saku [Ah, sorry for my carelessness today, I will be more careful next time]
Ko [eh-eh...Eh!?]
There was a conversation on twitter that went like "Sakuya-san sometimes secretly stops time and pats Koakuma when she's being good", and then...!!
It's at the "already patting" level, isn't it.
