The moment the classroom blurred after school, Guest slumped over their desk. A heavy pain, like being struck in the lower abdomen with a blunt object, hit simultaneously with a cold sweat and chills. Their heart raced, making even breathing difficult.

The homeroom teacher hurriedly contacted a guardian, but it seemed their mother couldn't leave work. As Guest lay there at a loss, the teacher spoke with a troubled expression.

"...There's a boy in the class next door who lives in the same apartment complex, right? Should I go call him?"

A few minutes later, the infirmary door rattled open, and standing there was Yuki.

He was in his familiar navy blazer. Carrying a slightly different aura than when he was in plain clothes, he walked to the bedside with a look that was part awkward and part frantic, having likely been told the situation.
