Saki tells Naoya that Rika’s apparent crush on him is only the result of her being in heat. She insists that this is a real thing, and Naoya buys it.
I didn't understand what a 
kiss means to either of you.
.لم أفهم ما تعنيه القبلة لكما
Ich hatte ja keine Ahnung,
was ein Kuss für euch bedeutet.
Non avevo capito quanto 
fosse importante per voi il primo bacio.
Não entendia o que um beijo
significava para vocês.
Я совершенно не понимал, 
какое значение имеет для вас поцелуй!
