Homare finds the solitary island where Shion washed ashore and the two are reunited. But there's no time to rejoice. With no food or water, succumbing to dehydration is only a matter of time... All they have is filthy water they find in a cave... In this dire situation, the two of them use a secret technique for rehydration!? Will Homare and Shion make it back to the island?
What happened today... let's make sure
to keep it a secret between the two of us.
لنبق ما حصل اليوم سرّاً بيننا
Was wir heute getan haben,
bleibt unser kleines Geheimnis.
Asegurémonos de que lo de hoy
quede entre nosotras.
Asegurémonos de que lo de hoy

Пусть то, что сегодня произошло,
