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.
To be honest, I was scared to ask you about it.
.للأمانة، كنتُ خائفة من أن أسألك عن الأمر
Ich hatte Angst davor,
die Wahrheit herauszufinden.
A essere onesta, 
avevo paura di chiederti spiegazioni.
A verdade é que fiquei com medo
de perguntar sobre isso.
Если честно,
мне было страшно тебя расспрашивать.
