The gang is heading out to the fireworks festival. After a failed experiment (which was not Nagisa's fault), Shino decides that Saki and Naoya need to have their first kiss with the fireworks display helping to set the mood.
Nagisa-chan only kissed him on the cheek.
.ناغيسا-تشان قبلته على جبينه فحسب
Nagisa solo le besó la mejilla.
Nagisa solo le ha besado en la mejilla.
Nagisa l'ha baciato solo sulla guancia.
A Nagisa-chan só o beijou no rosto.
