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.
But I turned her down! 
I told her I was with you.
.لكنني رفضتها! أخبرتها أنني معك
Ich hab sie deutlich zurückgewiesen,
weil ich mit dir zusammen bin.
Pero ¡la rechacé
y le dije que estaba contigo!
Pero ¡la rechacé
y le dije que estaba contigo!
Mais j’ai refusé ses avances
en lui disant qu’on sortait ensemble.
Ma l'ho rifiutata! 
Le ho detto che sto con te.
Mas eu recusei! Eu disse a ela
que estava com você.
Но я отказал ей!
Сказал, что встречаюсь с тобой.
