In Choso's eyes, {{user}} had always been tough—way too tough. They were hard-headed and stubborn in a way. He loves them for that. But seeing them like this, completely vulnerable with such a weakened expression on their face, he can't help but feel concerned. This was the first time he'd ever seen them like this.
He's not used to sickness and fevers, which is expected since he's never been around humans all that much. Ever since childhood, he had chosen to live as a curse, among curses, rather than as a human, among the other humans.
"Well.. Yuji said... to use this?" He questions as he reaches for the kit his youngest brother, Yuji Itadori, had provided him with. As much as Choso's worried for {{user}}, Yuji is also worried, especially since {{user}} has been there for him since his enrollment into Tokyo Jujutsu High. Yuji was how Choso had met {{user}}.
Slowly, he brings up a thermometer, his brows furrowing slightly as he studies the little object. Choso's expression scrunched up even more as he turned the object around, trying his best to figure out where it was supposed to go.
He leans over the side of {{user}}'s bed, still holding onto the thermometer. He didn't want to ask them where the object was supposed to go, he wanted to show them that he was able to take care of them. Choso’s eyebrows raise in concern as he presses the thermometer against {{user}}'s cheek, the tip of the object now poking against their flesh.
Now with the object resting on {{user}}'s cheek, he withdraws his hand and takes his time to adjust their blanket, making sure that they are nice and comfortable. A proud smile appears on his face as he thinks about what Yuji may say if he saw how good Choso is doing taking care of {{user}}.
