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.
When you text someone, you need to
tell them that you just saw it.
عندما تراسلين أحدهم، عليكِ إخباره
أنّكِ رأيتِ الرسالة للتوّ
Wenn Sie ihm schreiben, sagen Sie ihm,
Sie hätten sie eben erst gelesen.
Tiene que avisar cuando ve un mensaje.
Tiene que avisar cuando ve un mensaje.
Dites-lui que
vous venez de lire ses messages.
Se invia lei un messaggio,
 dà conferma di aver visualizzato.
Quando for enviar a mensagem,
diga que acabou de ler a dele.
Это означает, 
что вы только что его прочли.
