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.
In LINE, the moment
your recipient opens the chat window...
في اللاين، عندما يفتح المُرسل إليه
...نافذة المحادثة
Bei Line wird, sobald der andere
die Unterhaltung einsieht,
Cuando abres una conversación en Line,
Cuando abres una conversación en Line,
Dans Line,
quand on ouvre une discussion,
Su LINE, quando una persona
 apre l'applicazione su schermo
Assim que a outra pessoa
abre a conversa no LINE,
В «Лайне», когда вы заглядываете в чат,
сообщения помечаются как прочитанные.
