Things come to a head between Rena and Chizuru, which reminds Arata about a traumatic experience in his past.
I don't understand how they feel.
.لا أعرف كيف يشعرون
Ich kann ihre Gefühle
nicht nachvollziehen.
come si sentano le persone 
e tutto quel genere di cose.
Eu não entendo 
como elas se sentem.
и что они чувствуют.
