At the fireworks display, everyone puts their plans into motion and tries to make things work between Kazuomi and Rena. Meanwhile, a different pairing begins to take shape...
But if we end up separated, 
I'll regret not saying anything.
.ولكنّي سأندم على عدم قول شيء إن افترقنا
Aber wenn wir das nicht tun, werde ich
es ewig bereuen, es ihm nie gesagt zu haben.
Mas se acabarmos separados, eu vou 
me arrepender de não ter falado nada.
Но если мы разделимся,
я буду жалеть, что ничего не сказала.
