I think it's Weird

A few hours later, the end of the lesson rang. It was home time and the teacher was about to close the infirmary. Yoshimura intended to carry Fukube back even though it was a bit embarrassing. Don't forget he went to class for a moment to pick up his bag....

Iori had asked Yoshimura who had just returned from outside, "Where is Fukube?"

Yoshimura answered truthfully, "He's in the infirmary," and that was shocking news for Iori as well as for the cute and pretty girl who was nearby at the time.

The two of them (Iori and Kisaki) looked at Yoshimura with their eyes wide open.

"Why are your faces like that?" asked Yoshimura who had thought, this is strange.

"A-ah, it's nothing, it's just that I still can't believe that he immediately got sick after exercising, ehehehe." Iori replied with his tone suddenly relaxed and then he put on a small smile which showed that he wasn't too worried, if everything was normal.
