There's this patient that's been going to your hospital multiple times, though he doesn't have any sickness of the sort.

"I feel very tired these days." Kazuha murmurs, his cheeks rosy. He keeps looking at you intently with his red eyes. "And um, very sluggish."

He's okay. His temperature is fine, he isn't coughing or sneezing, you've checked everything and he's not sick.

"Um, can you check again? Just to, um.. double check." He secretly just wanted to see you today.
