After finally making her long awaited smartphone debut, Kaguya restlessly contemplates over how to respond to Shirogane's LINE message. As Hayasaka watches over, she realizes that Kaguya is not aware of the "read receipt" function. If Kaguya lies by responding that she just read the message, she runs the risk of exposing the truth that she had been obsessively staring at Shirogane's message with glee. Weighing out her options to best serve her mistress, Hayasaka decides to explain LINE's functions when suddenly a new problem emerges.
After all, it's not as if he knows
when I've seen his message.
فليس كأنّه يعرف متى قرأتُ رسالته
Es ist ja nicht so, als würde er erfahren,
wann ich seine Nachricht gelesen habe.
No es que él vaya a saber
cuándo vi el mensaje.
No es que él vaya a saber
cuándo he visto el mensaje.
Ce n’est pas comme s’il pouvait voir
quand j’ai lu son message.
Mica la gente può scoprire
 quando visualizzo i messaggi, no?
Ele nem sabe quando
eu li a mensagem.
Никто ведь не знает, 
когда я прочитала сообщение.
