Mei wants to talk one-on-one to Fuyuki, but Mawaru and Hiyori must be nearby to take care of her. "Anu, how's this?" May said it with fear. He really looks really bleak.
Then Kei patted Mei on the shoulder, "Say son. We're not just Fuyuki's friends here, maybe more precisely some kind of family."
"Yes, don't hesitate Kuriyama-san. I'll listen to what you want to say." Fuyuki replied. "Maybe I seem unfriendly to a lot of people, and I do really keep the image in front of my friends." He explained... Fuyuki who is currently close to the people who recognize him is 'Fuyuki who doesn't wear any masks.'
It means that Fuyuki's true self is like this, but it doesn't throw away her cool nature.
"Um... so... Are you really having diarrhea?" Mei asked to confirm it.
"Yes." Fuyuki replied briefly.
"I-that's very bad." May hesitated what she would say, she then asked something... "Nee, is diarrhea caused by food?"
