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 still couldn't hold back my feelings.
.لكني لم أستطع كبح مشاعري مع ذلك
Trotzdem konnte ich
meine Gefühle nicht im Zaum halten.
Pero no puedo evitar
sentir lo que siento.
Pero no puedo evitar
sentir lo que siento.
C’est plus fort que moi.
Ma non sono riuscita 
a soffocare i miei sentimenti.
Mas eu ainda não consegui
conter meus sentimentos.
Но я всё равно не сдержала
своих чувств.
