Hayato notices that Akane seems down, and suspects she's planning to quit. When he asks her about it, she responds with a defeated look, so he asks her to teach him how his grandma made coffee. His coldness makes Akane wonder what "family" truly is.
and if you've made up your mind, 
I won't stop you.
وإذا اتّخذتِ قراركِ، فلن أمنعكِ
Y si te decidiste, no te detendré.
Y si te has decidido, no te detendré.
E, se você já se decidiu,
não vou te impedir.
Если ты всё решила,
я не буду мешать.
