Erika and Sakaki manage to escape from under Sensei with her mother's guidance. Apparently, she's been making preparations, little by little, for Erika to run away one day. Erika learns of thoughts and feelings she didn't know her mother had.
After making contact with Mikado and the others, Erika tells them that she wants Sensei to stop doing the work they do, not just herself. Mikado decides to help, but it seems that Hiyakawa can't understand Erika and Mikado's feelings.
To me, it looks like you aren't 
aware of your own emotions.
تبدو لي أنّك لا تدرك مشاعرك
Es wirkt, als würdest du dir deiner
eigenen Gefühlen nicht bewusst sein.
Yo solo veo que no te das cuenta
de tus propias emociones.
Yo solo veo que no te das cuenta
de tus propias emociones.
Tu me donnes l’impression
d’ignorer ce que tu ressens.
A me sembra che tu non ti renda conto
 delle tue stesse emozioni.
Para mim, parece que você
não está ciente de suas emoções.
Такое ощущение,
что ты не замечаешь своих же чувств.
