Runa invites Ryuto to the beach to celebrate their one-month anniversary in the sun. When nervous Ryuto is just starting to relax with his radiant, bikini-clad girlfriend, a typhoon strands the two and forces them to spend the night together in an inn.
Even if all boys on Earth 
cheated on their girlfriends,
،حتى إن خان كل الفتيان على وجه الأرض حبيباتهم
Selbst wenn alle Männer
auf der Welt fremdgehen,
Aunque todos los chicos de la Tierra
fueran infieles,
Aunque todos los chicos de la Tierra
fueran unos infieles,
Même si tous les mecs
trompaient leur nana,
Anche se ogni ragazzo sulla Terra
tradisse la sua fidanzata,
Mesmo que todos os garotos
do mundo traíssem suas namoradas,
Даже если бы все парни в мире
изменяли своим девушкам,
ต่อให้ผู้ชายทุกคนบนโลกนี้นอกใจเรา
