The person who called Ryuto to the gym at night was actually Maria. She confesses her desperation to become Ryuto's first, even if that means dressing and acting like Runa. Ryuto is shocked. As the two talk it out, someone else watches from the shadows.
My battery died, 
so I'm borrowing Maria's phone.
.نفد شحني، لذا أستعير هاتف ماريا
Sie hat mir ihr Smartphone geliehen,
weil meinem der Saft ausgegangen ist.
Me quedé sin batería
y le pedí el suyo a Maria.
Me he quedado sin batería
y le he pedido el suyo a Maria.
J’ai plus de batterie
et j’utilise le portable de Maria.
Siccome mi è morto il caricabatterie,
Maria mi ha prestato il suo cellulare.
O carregador do meu telefone morreu, então
peguei emprestado o celular da Maria.
У меня зарядник сломался,
так что звоню с телефона Марии.
มือถือฉันแบตหมดน่ะ ก็เลยยืมมือถือของมาเรีย
