Hakari and Karane learn that Rentaro hasn't had his first kiss yet. They may both be his girlfriends, but they still want his first kiss for themselves!
You're not an open book, 
you're the whole library!
!لستِ كتاباً مفتوحاً، أنتِ المكتبة بأكملها
Ein Volltreffer wie aus dem Bilderbuch!
En plein dans le mille !
Alla faccia del libro aperto!
Nem é um livro aberto,
é a biblioteca inteira!
В яблочко с километра попал!
