Yuta starts to get worried about Saki and asks Akiko for advice. Akiko tells him that he should take Saki out for a break now and then, even if he has to insist. Later, when Yuta tries to talk to Saki about the pool trip with Maaya, Saki reacts harshly.
When we decided to stop 
talking formally to each other.
عندما قرّرنا التوقُّف عن التكلّم مع بعضنا
الآخر بشكلٍ رسميّ
Als wir ausgemacht haben, nicht mehr
so förmlich miteinander zu reden.
Quand on a décidé
de plus faire de manières.
Quando abbiamo deciso di smetterla
con le formalità.
Quando decidimos que íamos
encerrar as formalidades entre nós.
Когда мы решили общаться нормально.
