Saki asks her classmate Narasaka Maaya to come over after school and help her study. Yuta decides to make dinner for a change so Saki can keep studying. Maaya helps Yuta with the recipe and then starts interrogating him about his relationship with Saki.
But you're basically strangers, right? 
You aren't even related by blood.
لكنّكما غريبان جوهريّاً، صحيح؟
لستُما مرتبطين بالدّم حتّى
Aber ihr seid doch quasi Fremde.
Ihr seid ja nicht blutsverwandt.
Pero son desconocidos, ¿no?
No son hermanos biológicos.
Pero sois desconocidos, ¿no?
No os une la sangre.
Vous êtes presque des inconnus
même pas liés par le sang.
Però siete due sconosciuti
Mas vocês são basicamente estranhos.
Não tem nenhuma relação de sangue.
Но вы же почти чужие люди. 
Даже не кровные родственники.
